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 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-antivirus/clamav < 0.94 >= 0.94 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Hanno boeck reported an error in libclamav/chmunpack.c when processing |
| 38 |
CHM files (CVE-2008-1389). Other unspecified vulnerabilites were also |
| 39 |
reported, including a NULL pointer dereference in libclamav |
| 40 |
(CVE-2008-3912), memory leaks in freshclam/manager.c (CVE-2008-3913), |
| 41 |
and file descriptor leaks in libclamav/others.c and libclamav/sis.c |
| 42 |
(CVE-2008-3914). |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
A remote attacker could entice a user or automated system to scan a |
| 48 |
specially crafted CHM, possibly resulting in a Denial of Service |
| 49 |
(daemon crash). The other attack vectors mentioned above could also |
| 50 |
result in 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" |
| 64 |
|
