Synopsis |
16 |
======== |
17 |
|
18 |
Two vulnerabilities in ClamAV may allow for the remote execution of |
19 |
arbitrary code or a Denial of Service. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Clam AntiVirus is a free anti-virus toolkit for UNIX, designed |
25 |
especially for e-mail scanning on mail gateways. |
26 |
|
27 |

Description |
36 |
=========== |
37 |
|
38 |
Moritz Jodeit reported an off-by-one error within the |
39 |
get_unicode_name() function in libclamav/vba_extract.c when processing |
40 |
VBA project files (CVE-2008-5050). Ilja van Sprundel reported an |
41 |
infinite recursion error within the cli_check_jpeg_exploit() function |
42 |
in libclamav/special.c when processing JPEG files (CVE-2008-5314). |
43 |
|
44 |
Impact |
45 |
====== |
46 |
|
47 |
A remote attacker could send a specially crafted VBA or JPEG file to |
48 |
the clamd daemon, possibly resulting in the remote execution of |
49 |
arbitrary code with the privileges of the user running the application |
50 |
or a Denial of Service. |
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-0.94.2" |
