- A vulnerability in ClamAV's chm-parser allowed remote attackers to
cause a denial of service (application crash) via a malformed CHM file
(CVE-2008-1389).
- A vulnerability in libclamav would allow attackers to cause a
denial of service via vectors related to an out-of-memory condition
(CVE-2008-3912).
- Multiple memory leaks were found in ClamAV that could possibly allow
attackers to cause a denial of service via excessive memory consumption
(CVE-2008-3913).
- A number of unspecified vulnerabilities in ClamAV were reported that
have an unknown impact and attack vectors related to file descriptor
leaks (CVE-2008-3914).
various OpenBSD patches rolled in upstream. thanks to sturm@
for looking over systrace.filter (needed for the test of sendmsg()
in configure to enable FD passing).
- fixes DoS with MailFollowURLs (CVE-2008-2713)
- improves handling of PDF, CAB, RTF, OLE2 and HTML files
and includes various bugfixes for 0.93 issues.
"if it works" mbalmer@
least one highly critical (remote). See http://secunia.com/advisories/29000
for details.
Thanks to kurt@ for helping analyzing the threaded code issues.
Note to -stable ports maintainers: This should probably be put into -stable
since the ClamAV people do not provide virus data to outdated scan engines.
ok simon
fixes:
- ClamAV CAB File Unstore Buffer Overflow Vulnerability
- File descriptor leak in CHM handler
- PDF fd leak
From the original annoucement:
**Important note**: on April 16th CHM, CAB and PDF handlers will be
disabled for 0.90 and 0.90.1 users through the dynamic engine
configuration module (DCONF). Please upgrade to 0.90.2 immediately.
- Build a new version even if the old one is still installed
- Only chmod 700 the /var/clamav/quantine directory
