Description Tomas Hoger 2009-04-09 10:13:48 UTC

Upstream clamav version 0.95.1 seems to fix two bugs that may cause clamscan / clamd to crash when scanning certain inputs:

Crash when scanning a malformed file packed with UPack

Upstream bug:
https://wwws.clamav.net/bugzilla/show_bug.cgi?id=1552


cli_url_canon buffer overflow (this only seems to affect 0.95.x)

Upstream bug:
https://wwws.clamav.net/bugzilla/show_bug.cgi?id=1553


Both fixed upstream in:
svn diff -c 5032 http://svn.clamav.net/svn/clamav-devel/

CVE-2009-1371:
The CLI_ISCONTAINED macro in libclamav/others.h in ClamAV before
0.95.1 allows remote attackers to cause a denial of service
(application crash) via a malformed file with UPack encoding.

CVE-2009-1372
Stack-based buffer overflow in the cli_url_canon function in
libclamav/phishcheck.c in ClamAV before 0.95.1 allows remote attackers
to cause a denial of service (application crash) and possibly execute
arbitrary code via a crafted URL.
