The main security vulnerabilities addressed in 1.3.33 are:
* CAN-2004-0940 (cve.mitre.org)
Fix potential buffer overflow with escaped characters in SSI tag string.
* CAN-2004-0492 (cve.mitre.org)
Reject responses from a remote server if sent an invalid
(negative) Content-Length.
New features
* Win32: Improve error reporting after a failed attempt to
spawn a piped log process or rewrite map process.
* Added new compile-time flag: UCN_OFF_HONOR_PHYSICAL_PORT. It
controls how UseCanonicalName Off determines the port value if
the client doesn't provide one in the Host header. If defined
during compilation, UseCanonicalName Off will use the physical
port number to generate the canonical name. If not defined, it
tries the current Port value followed by the default port for
the current scheme.
The following bugs were found in Apache 1.3.31 (or earlier) and
have been fixed in Apache 1.3.33:
* mod_rewrite: Fix query string handling for proxied URLs. PR 14518.
* mod_rewrite: Fix 0 bytes write into random memory position. PR 31036.
* mod_digest: Fix nonce string calculation since 1.3.31 which
would force re-authentication for every connection if
AuthDigestRealmSeed was not configured. PR 30920.
* Fix trivial bug in mod_log_forensic that caused the child to
seg fault when certain invalid requests were fired at it with
forensic logging is enabled. PR 29313.
* No longer breaks mod_dav, frontpage and others. Repair a
patch in 1.3.31 which prevented discarding the request body
for requests that will be keptalive but are not currently
keptalive. PR 29237.

Apache 1.3.31 Major changes
Security vulnerabilities
* CAN-2003-0987 (cve.mitre.org)
In mod_digest, verify whether the nonce returned in the client
response is one we issued ourselves. This problem does not affect
mod_auth_digest.
* CAN-2003-0020 (cve.mitre.org)
Escape arbitrary data before writing into the errorlog.
* CAN-2004-0174 (cve.mitre.org)
Fix starvation issue on listening sockets where a short-lived
connection on a rarely-accessed listening socket will cause a
child to hold the accept mutex and block out new connections until
another connection arrives on that rarely-accessed listening socket.
* CAN-2003-0993 (cve.mitre.org)
Fix parsing of Allow/Deny rules using IP addresses without a
netmask; issue is only known to affect big-endian 64-bit
platforms
New features
New features that relate to specific platforms:
* Linux 2.4+: If Apache is started as root and you code
CoreDumpDirectory, core dumps are enabled via the prctl() syscall.
New features that relate to all platforms:
* Add mod_whatkilledus and mod_backtrace (experimental) for
reporting diagnostic information after a child process crash.
* Add fatal exception hook for running diagnostic code after a
crash.
* Forensic logging module added (mod_log_forensic)
* '%X' is now accepted as an alias for '%c' in the
LogFormat directive. This allows you to configure logging
to still log the connection status even with mod_ssl
Bugs fixed
The following noteworthy bugs were found in Apache 1.3.29 (or earlier)
and have been fixed in Apache 1.3.31:
* Fix memory corruption problem with ap_custom_response() function.
The core per-dir config would later point to request pool data
that would be reused for different purposes on different requests.
* mod_usertrack no longer inspects the Cookie2 header for
the cookie name. It also no longer overwrites other cookies.
* Fix bug causing core dump when using CookieTracking without
specifying a CookieName directly.
* UseCanonicalName off was ignoring the client provided
port information.
SECURITY [CAN-2003-0020]: escape arbitrary data before writing into the errorlog
The three patches are from Apache cvs.
http://cvs.apache.org/viewcvs.cgi/apache-1.3/src/
Also bump PKGREVISION too.
Major changes since 1.3.28:
Security vulnerabilities
* CAN-2003-0542 (cve.mitre.org)
Fix buffer overflows in mod_alias and mod_rewrite which occurred if
one configured a regular expression with more than 9 captures.
Bugs fixed
The following noteworthy bugs were found in Apache 1.3.28 (or earlier)
and have been fixed in Apache 1.3.29:
* Within ap_bclose(), ap_pclosesocket() is now called
* consistently
for sockets and ap_pclosef() for files. Also, closesocket()
is used consistenly to close socket fd's. The previous
confusion between socket and file fd's would cause problems
with some applications now that we proactively close fd's to
prevent leakage.
* Fixed mod_usertrack to not get false positive matches on the
user-tracking cookie's name.
* Prevent creation of subprocess Zombies when using CGI wrappers
such as suEXEC and cgiwrap.
- SECURITY: CAN-2003-0460 (cve.mitre.org)
Fix the rotatelogs support program on Win32 and OS/2 to ignore
special control characters received over the pipe. Previously
such characters could cause it to quit logging and exit.
[André Malo]
- Prevent the server from crashing when entering infinite loops. The
new LimitInternalRecursion directive configures limits of subsequent
internal redirects and nested subrequests, after which the request
will be aborted. PR 19753 (and probably others).
[William Rowe, Jeff Trawick, Jim Jagielski, André Malo]
- Fix NULL-pointer issue in ab when parsing an incomplete or non-HTTP
response. PR 21085. [Glenn Nielsen <glenn@apache.org>, André Malo]
- Removed BIND_NOSTART from HP/UX shl_load() logic for loadable
Apache modules, so that statics are initialized when the module
is loaded (especially critical for c++ modules on HPUX.)
[William Rowe, Noah Arliss <narliss@netegrity.com>]
- Win32 build system changes; always recompile buildmark.c (used for
Apache -v 'server built' messages) even when Apache is built from
within the IDE; build test_char.h and uri_delims.h from within the
ApacheCore.dsp project. PR 12706. [William Rowe]
- Introduce Win32 .pdb diagnostic symbols into the Apache 1.3 build
(as created in Apache 2.0.45 and later.) Makes debugging and
analysis of crash dumps and Dr. Watson logs trivial. Requires the
Win32 binary builder to set aside the exact .pdb files that match
the released binaries (.exe/.so files) for reference by users and
developers. [William Rowe]
- Make sure the accept mutex is released before calling child exit
hooks and cleanups. Otherwise, modules can segfault in such code
and, with pthread mutexes, leave the server deadlocked. Even if
the module doesn't segfault, if it performs extensive processing
it can temporarily prevent the server from accepting new
connections. [Jeff Trawick]
- Fix mod_rewrite's handling of absolute URIs. The escaping routines
now work scheme dependent and the query string will only be
appended if supported by the particular scheme. [André Malo]
- Use appropriate language codes for Czech (cs) and Traditional Chinese
(zh-tw) in default config files. PR 9427. [André Malo]
- Don't block synchronous signals (e.g., SIGSEGV) while waiting for
and holding a pthread accept mutex. [Jeff Trawick]
- AIX: Change the default accept mechanism from pthread back to
fcntl. Idle child cleanup doesn't work when the child selected
for termination by the parent is waiting on a pthread mutex, and
because the AIX kernel's notion of hot process is apparently the
same as Apache's, it is common for the Apache parent to continually
select a child for termination that the kernel will leave waiting
on the mutex for extended periods of time. There are other
concerns with pthread mutexes as well, such as the ability to
deadlock the server if a child process segfaults while holding the
mutex. [Jeff Trawick]
- Fix a pair of potential buffer overflows in htdigest
[Martin Schulze <joey@infodrom.org>, Thom May]
- A newly created child now has a start_time of 0, to prevent
mod_status from displaying a bogus value for the "time to

- When using Redirect in directory context, append requested query
string if there's no one supplied by configuration. PR 10961.

- Unix build: Add support for environment variable
EXTRA_LDFLAGS_SHLIB, which allows the user to add to the hard-coded
ld flags specified for DSOs. Compare with the existing LDFLAGS_SHLIB
environment variable, which allows the user to completely replace the
hard-coded ld flags specified for DSOs. [Jeff Trawick]
- mod_auth_digest no longer tries to guess AuthDigestDomain, if it's
not specified. Now it assumes "/" as already documented. PR 16937.

"Options FollowSymlinks" (or SymlinksIfOwnermatch) is set.
PR 12395. [André Malo]
- Change the log messages for setsockopt(TCP_NODELAY) and
getsockname() failures to log the client IP address and to
change the log level to debug. [Jeff Trawick]
- Correction to mod_negotation for Win32, OS2, Netware etc, where
case insensitive requests such as the HEADER or README search
from autoindex would fail to match HEADER.html (because the
system internally looked for the case-sensitive header.* pattern.)
PR 7300 [William Rowe]
- Correction to mod_autoindex so that only text/* files (prefering
/html, then /plain, then some other flavor) can be recovered
from a multiview-based HEADER or README subrequest.
[William Rowe]
- Improvements to mod_usertrack that allows for a regular (verbose)
as well as "compact" version of the tracking cookie (the new
'CookieFormat' directive), and the ability to prepend a string
to the cookie via the 'CookiePrefix' directive.
[Pål Løberg <pallo@initio.no>, with cleanup by Jim Jagielski]
- Certain 3rd party modules would bypass the Apache API and not
invoke ap_cleanup_for_exec() before creating sub-processes.
To such a child process, Apache's file descriptors (lock
fd's, log files, sockets) were accessible, allowing them
direct access to Apache log file etc. Where the OS allows,
we now add proactive close functions to prevent these file
descriptors from leaking to the child processes.
[Jim Jagielski, Martin Kraemer]
- Prevent obscenely large values of precision in ap_vformatter
from clobbering a buffer. [Sander Striker, Jim Jagielski]
- NetWare: implemented ap_os_default_port() to resolve the
correct default port based on the request method. This fixes
a URL reconstruction problem on a redirect.
[Pavel Novy (novy@feld.cvut.cz)]
- Added new ap_register_cleanup_ex() API function which allows
for a "magic" cleanup function to be run at register time
rather than at cleanup time. Also added the
ap_note_cleanups_for_(socket|fd|file)_ex() API functions
which allows for control over whether that magic cleanup
should be called or not. This does not change the default
behavior of the non-"ex" function (eg: ap_register_cleanup).

- PORT: Take advantage of OpenBSD's arc4random() function for the
initial secret [Henning Brauer <hb-apache-dev at bsws.de>]
- If Listen directive is not a port, but just an IP, emit an
error condition as this case is ambiguous.
[Rich Bowen, Justin Erenkrantz, Cliff Woolley]
- Update timeout algorithm in free_proc_chain. If a subprocess
did not exit immediately, the thread would sleep for 3 seconds
before checking the subprocess exit status again. In a very
common case when the subprocess was an HTTP server CGI script,
the CGI script actually exited a fraction of a second into the 3
second sleep, which effectively limited the server to serving one
CGI request every 3 seconds across a persistent connection.

- mod_setenvif: Add SERVER_ADDR special keyword to allow
envariable setting according to the server IP address

and above. Update AIX configure logic to allow higher AIX
release numbers without having to change Apache.

Prevent a cross-site scripting vulnerability in the default
error page. The issue could only be exploited if the directive
UseCanonicalName is set to Off and a server is being run at

a malicious server. Reported by David Wagner. [Jim Jagielski]
- SECURITY CAN-2002-0839 (cve.mitre.org)
Add the new directive 'ShmemUIDisUser'. By default, Apache
will no longer set the uid/gid of SysV shared memory scoreboard
to User/Group, and it will therefore stay the uid/gid of
the parent Apache process. This is actually the way it should
be, however, some implementations may still require this, which
can be enabled by 'ShmemUIDisUser On'. Reported by iDefense.
