Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities in ClamAV may result in a Denial of Service. |
19 |
|
20 |
Background |
21 |
========== |
22 |
|
23 |
Clam AntiVirus is a free anti-virus toolkit for UNIX, designed |
24 |
especially for e-mail scanning on mail gateways. |
25 |
|
26 |
Affected packages |
27 |

Description |
35 |
=========== |
36 |
|
37 |
Damian Put has discovered an out-of-bounds memory access while |
38 |
processing Petite files (CVE-2008-2713, CVE-2008-3215). Also, please |
39 |
note that the 0.93 ClamAV branch fixes the first of the two attack |
40 |
vectors of CVE-2007-6595 concerning an insecure creation of temporary |
41 |
files vulnerability. The sigtool attack vector seems still unfixed. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A remote attacker could entice a user or automated system to scan a |
47 |
specially crafted Petite file, possibly resulting in a Denial of |
48 |
Service (daemon crash). Also, the insecure creation of temporary files |
49 |
vulnerability can be triggered by a local user to perform a symlink |
50 |
attack. |
51 |
|
52 |
Workaround |
53 |
========== |
54 |
|
55 |
There is no known workaround at this time. |
56 |
|
57 |
Resolution |
58 |
========== |
59 |
|
60 |
All ClamAV users should upgrade to the latest version: |
61 |
|
62 |
# emerge --sync |
63 |
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.93.3" |
64 |
