Description Tomas Hoger 2009-04-09 09:04:46 UTC

Upstream clamav version 0.95 fixes few security issues:

CVE-2008-6680:
libclamav/pe.c in ClamAV before 0.95 allows remote attackers to cause
a denial of service (crash) via a crafted EXE file that triggers a
divide-by-zero error. 

Upstream bug:
https://wwws.clamav.net/bugzilla/show_bug.cgi?id=1335 

Upstream fix:
svn diff -c 4980 http://svn.clamav.net/svn/clamav-devel/


CVE-2009-1270:
libclamav/untar.c in ClamAV before 0.95 allows remote attackers to
cause a denial of service (infinite loop) via a crafted file that
causes (1) clamd and (2) clamscan to hang. 

Upstream bug:
https://wwws.clamav.net/bugzilla/show_bug.cgi?id=1462

Upstream fix:
svn diff -c 4981 http://svn.clamav.net/svn/clamav-devel/

Comment 1 Tomas Hoger 2009-04-09 09:08:26 UTC

For the sake of completeness...

0.95 also fixes following RAR check bypass, though RAR code is removed from Fedora build due to licensing resons.

CVE-2009-1241:
Unspecified vulnerability in ClamAV before 0.95 allows remote attackers to bypass detection of malware via a modified RAR archive.

Upstream bug:
https://wwws.clamav.net/bugzilla/show_bug.cgi?id=1467

Upstream fix:
svn diff -c 4977 http://svn.clamav.net/svn/clamav-devel/

Comment 2 Tomas Hoger 2009-04-09 09:09:05 UTC

Both CVE-2008-6680 and CVE-2009-1270 exist also in the oldest clamav version currently shipped - 0.93.3 in F9.

Comment 3 Robert Scheck 2009-04-10 21:41:16 UTC

1963 (clamav): Build on target fedora-5-epel succeeded.
1965 (clamav): Build on target fedora-4-epel succeeded.

Comment 4 Vincent Danen 2009-12-03 20:46:04 UTC

Only Fedora 10 (0.94.2) is still affected by this issue; Fedora 11 has 0.95.2 and EPEL has 0.95.1.
