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.
NetBSD Packages Collection (pkgsrc) changes:
* Modify French page in same way as the English page. Translation
provided by Remi Zara <remi_zara@mac.com> in private e-mail.
* Use EAPI patches from mod_ssl-2.8.4-1.3.20.
* Unify repeated SED replacement info for config.layout, apache.sh,
DEINSTALL, and INSTALL into one location, FILES_SUBST.
* Modify patch to apxs to use 0:0 instead of root:wheel, as some
non-NetBSD systems don't have a wheel group.
The general bug fixes:
* Eliminate a potential segfault if an invalid floating point value
is passed to the ap_snprintf() function, on platforms supporting
isnan() and isinf().
* Fix a possible segfault at startup in the detection of a default
ServerName or IP string when no ServerName was specified.
* Fixed mod_proxy to retain empty headers, as allowed by RFC2068.
* Properly resolve the location of ndbm on Linux and some glibc2
builds, where ndbm.h is in the nonstandard db1/ subdir.
The main new features include:
* Enhanced rotatelogs to allow a UTC offset to be specified, and
the format logfile names with human-readable date/time stamps.
* Added the NOESCAPE (NS) flag to RewriteRule, to disable *all*
normal URI escaping. Note incautious use can give unexpected
results or introduce security risks.
* Added the '\' character to RewriteRule to allow escaping of
special characters. Allows embedding of both the '$' and '%'
characters in the results, so 'foo\$1' translates to 'foo$1'
rather than 'foo\<value of $1>'.
* Added the -V flag to suexec, to display the compile-time settings
with which it was built. (Only valid for root or the HTTPD_USER
username.)
* Introduced EBCDIC conversion configuration options, controlling the
conversion based on MIME type or file suffix.
-) Remove patch to avoid dlclose()ing on NetBSD. The mod_perl vs. perl CGI
mis-interaction seems to be gone and I wasn't able to reproduce it on my
system.
*) Fix the declaration of the module structure in mod_example.
*) Fix the handling of variable expansion look-ahead in mod_rewrite,
i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
more complicated nested RewriteMap lookups.
*) mod_status now respects ?refresh=n of 1 or greater. If the given
refresh value is not a number, ?refresh is set to 1 second.
*) Accomodate an out-of-space condition in the piped logs and the
rotatelogs.c code, and no longer churn log processes for this condition.
*) Make cgi-bin work as a regular directory when using mod_vhost_alias
with no VirtualScriptAlias directives.
*) Move the check of the Expect request header field after the hook
for ap_post_read_request, since that is the only opportunity for
modules to handle Expect extensions.
*) Eliminate caching problems of mod_autoindex results, so the last
modified date of the directory is returned as the Last-Modified
and ETag HTTP header tags are sent if IndexOptions TrackModified
directive/option is used.
*) Correct an issue with Alias and ScriptAlias directives that
file path arguments were not normalized in canonical form.
This correction makes no attempt to normalize regular expression
forms of Alias or ScriptAlias.
*) Add a new LogFormat directive, %c, that will log connection
status at the end of the response.
*) Update the mime.types file to the registered media types as of 2000-10-19.
*) Restore functionality broken by the mod_rewrite security fix:
rewrite map lookup keys and default values are now expanded
so that the lookup can depend on the requested URI etc.
The security fixes are:
* A problem with the Rewrite module, mod_rewrite, allowed access to
any file on the web server under certain circumstances
* The handling of Host: headers in mass virtual hosting
configurations, mod_vhost_alias, could allow access to any file on
the server
* If a cgi-bin directory is under the document root, the source to
the scripts inside it could be sent if using mass virtual hosting
The main new features include:
* Support for a directory-based configuration system. If any of the
configuration directives point to directories instead of files,
all files in that directory (and in subdirectories) will be also
parsed as configuration files
* Support name-based virtual hosting without needing to specify an
IP address in the Apache configuration file. This enables sites
that use dynamic IP addresses to support name-based virtual
hosting as well as allowing identical machines to share a
configuration file, say in a load-balanced cluster
* The SetEnvIf and BrowserMatch range of directives are now able to
be used in .htaccess files.
* Administrators who are nervous about their full server version
details being public can use the new keyword 'ProductOnly' in the
ServerTokens directive. This keyword forces the server to only
return the string "Apache" as the server version.
* The new digest authentication module, mod_auth_digest has had a
number of fixes and upgrades applied
EAPI didn't change so no need to change Apache's version number.
Also standardize package builds to have Apache listen on ports 80/443
regardless of UID of user that builds the package, and make MAINTAINER
point to me.
