Update clamav to 0.102.1.
## 0.102.1
ClamAV 0.102.1 is a security patch release to address the following issues.
- Fix for the following vulnerability affecting 0.102.0 and 0.101.4 and prior:
- [CVE-2019-15961](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-15961)
A Denial-of-Service (DoS) vulnerability may occur when scanning a specially
crafted email file as a result of excessively long scan times. The issue is
resolved by implementing several maximums in parsing MIME messages and by
optimizing use of memory allocation.
- Build system fixes to build clamav-milter, to correctly link with libxml2 when
detected, and to correctly detect fanotify for on-access scanning feature
support.
- Signature load time is significantly reduced by changing to a more efficient
algorithm for loading signature patterns and allocating the AC trie.
Patch courtesy of Alberto Wu.
- Introduced a new configure option to statically link libjson-c with libclamav.
Static linking with libjson is highly recommended to prevent crashes in
applications that use libclamav alongside another JSON parsing library.
- Null-dereference fix in email parser when using the `--gen-json` metadata
option.
- Fixes for Authenticode parsing and certificate signature (.crb database) bugs.
Special thanks to the following for code contributions and bug reports:
- Alberto Wu
- Joran Dirk Greef
- Reio Remma
* The On-Access Scanning feature has been migrated out of clamd and
into a brand new utility named clamonacc, which is disabled in this
package as it is for Linux only.
* The freshclam database update utility has undergone a significant
update. This includes:
+ Added support for HTTPS.
+ Support for database mirrors hosted on ports other than 80.
+ Removal of the mirror management feature (mirrors.dat).
+ An all new libfreshclam library API.
* Added support for extracting ESTsoft .egg archives. This feature is
new code developed from scratch using ESTsoft's Egg-archive
specification and without referencing the UnEgg library provided by
ESTsoft. This was necessary because the UnEgg library's license
includes restrictions limiting the commercial use of the UnEgg library.

This release includes 3 extra security related bug fixes that do not
apply to prior versions. In addition, it includes a number of minor bug
fixes and improvements.
* Fixes for the following vulnerabilities affecting 0.101.1 and
prior:
+ CVE-2019-1787: An out-of-bounds heap read condition may occur
when scanning PDF documents. The defect is a failure to
correctly keep track of the number of bytes remaining in a
buffer when indexing file data.
+ CVE-2019-1789: An out-of-bounds heap read condition may occur
when scanning PE files (i.e. Windows EXE and DLL files) that
have been packed using Aspack as a result of inadequate
bound-checking.
+ CVE-2019-1788: An out-of-bounds heap write condition may occur
when scanning OLE2 files such as Microsoft Office 97-2003
documents. The invalid write happens when an invalid pointer
is mistakenly used to initialize a 32bit integer to zero. This
is likely to crash the application.
* Fixes for the following ClamAV vulnerabilities:
+ CVE-2018-15378: Vulnerability in ClamAV's MEW unpacking
feature that could allow an unauthenticated, remote attacker
to cause a denial of service (DoS) condition on an affected
device. Reported by Secunia Research at Flexera.
+ Fix for a 2-byte buffer over-read bug in ClamAV's PDF parsing
code. Reported by Alex Gaynor.
* Fixes for the following vulnerabilities in bundled third-party
libraries:
+ CVE-2018-14680: An issue was discovered in mspack/chmd.c in
libmspack before 0.7alpha. It does not reject blank CHM
filenames.
+ CVE-2018-14681: An issue was discovered in kwajd_read_headers
in mspack/kwajd.c in libmspack before 0.7alpha. Bad KWAJ file
header extensions could cause a one or two byte overwrite.
+ CVE-2018-14682: An issue was discovered in mspack/chmd.c in
libmspack before 0.7alpha. There is an off-by-one error in the
TOLOWER() macro for CHM decompression.
+ Additionally, 0.100.2 reverted 0.100.1's patch for
CVE-2018-14679, and applied libmspack's version of the fix in
its place.
* Fixes for the following CVE's:
+ CVE-2017-16932: Vulnerability in libxml2 dependency (affects
ClamAV on Windows only).
+ CVE-2018-0360: HWP integer overflow, infinite loop
vulnerability. Reported by Secunia Research at Flexera.
+ CVE-2018-0361: ClamAV PDF object length check, unreasonably
long time to parse relatively small file. Reported by aCaB.

ClamAV 0.99.4 is a hotfix release to patch a set of vulnerabilities.
- fixes for the following CVE's: CVE-2012-6706, CVE-2017-6419,
CVE-2017-11423, CVE-2018-0202, and CVE-2018-1000085.
- also included are 2 fixes for file descriptor leaks as well fixes for
a handful of other important bugs, including patches to support g++ 6, C++11.
If pcre2 is installed, configure finds pcre2-config in /usr/pkg/bin,
even though it is not include via bl3, resulting in a build failure.
There's no reason to avoid moving to pcre2, and it's easier than
making clamav not find it.
- Move PKGREVISION (unchanged) to Makefiles.
- Fix used-by annotation.
- Add PATCHDIR so clamav-doc has consistent distinfo/patches (even
though clamav-doc just copies files that aren't patched).
clamav defines a gets macro, which confuses fortify. Until resolved,
disable fortify so that it builds. (Note that SSP is still enabled;
clamav with SSP and without FORTIFY appears to work.)

- Various build problems on Solaris, OpenBSD, AIX.
- Crashes of clamd on Windows and Mac OS X platforms when reloading the virus signature database.
- Infinite loop in clamdscan when clamd is not running.
- Freshclam failure on Solaris 10.
- Buffer underruns when handling multi-part MIME email attachments.
- Configuration of OpenSSL on various platforms.
- Name collisions on Ubuntu 14.04, Debian sid, and Slackware 14.1.
- Linking issues with libclamunrar
- Support for common raw disk image formats using 512 byte sectors,
specifically GPT, APM, and MBR partitioning.
- Experimental support of OpenIOC files. ClamAV will now extract file
hashes from OpenIOC files residing in the signature database location,
and generate ClamAV hash signatures. ClamAV uses no other OpenIOC
features at this time. No OpenIOC files will be delivered through
freshclam. See openioc.org and iocbucket.com for additional information
about OpenIOC.
- All ClamAV sockets (clamd, freshclam, clamav-milter, clamdscan, clamdtop)
now support IPV6 addresses and configuration parameters.
- Use OpenSSL file hash functions for improved performance. OpenSSL
is now prerequisite software for ClamAV 0.98.3.
- Improved detection of malware scripts within image files. Issue reported
by Maarten Broekman.
- Change to circumvent possible denial of service when processing icons within
specially crafted PE files. Icon limits are now in place with corresponding
clamd and clamscan configuration parameters. This issue was reported by
Joxean Koret.
- Improvements to the fidelity of the ClamAV pattern matcher, an issue
reported by Christian Blichmann.
- Opt-in collection of statistics. Statistics collected are: sizes and MD5
hashes of files, PE file section counts and section MD5 hashes, and names
and counts of detected viruses. Enable statistics collection with the
--enable-stats clamscan flag or StatsEnabled clamd configuration
parameter.
- Improvements to ClamAV build process, unit tests, and platform support with
assistance and suggestions by Sebastian Andrzej Siewior, Scott Kitterman,
and Dave Simonson.
- Patch by Arkadiusz Miskiewicz to improve error handling in freshclam.
- ClamAV 0.98.3 also includes miscellaneous bug fixes and documentation
improvements.
quality improvements. These include:
- Extraction, decompression, and scanning of files within Apple Disk Image (DMG) format.
- Extraction, decompression, and scanning of files within Extensible Archive (XAR) format.
XAR format is commonly used for software packaging, such as PKG and RPM, as well as
general archival.
- Decompression and scanning of files in "Xz" compression format.
- Improvements and fixes to extraction and scanning of ole formats.
- Option to force all scanned data to disk. This impacts only a few file types where
some embedded content is normally scanned in memory. Enabling this option
ensures that a file descriptor exists when callback functions are used, at a small
performance cost. This should only be needed when callback functions are used
that need file access.
- Various improvements to ClamAV configuration, support of third party libraries,
and unit tests.
