Synopsis |
16 |
======== |
17 |
|
18 |
ClamAV contains multiple vulnerabilities that could lead to remote |
19 |
execution of arbitrary code or cause an application crash. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
ClamAV is a GPL virus scanner. |
25 |
|
26 |
Affected packages |
27 |
================= |
28 |
|
29 |
------------------------------------------------------------------- |
30 |
Package / Vulnerable / Unaffected |
31 |
------------------------------------------------------------------- |
32 |
1 app-antivirus/clamav < 0.88.1 >= 0.88.1 |

|
34 |
Description |
35 |
=========== |
36 |
|
37 |
ClamAV contains format string vulnerabilities in the logging code |
38 |
(CVE-2006-1615). Furthermore Damian Put discovered an integer overflow |
39 |
in ClamAV's PE header parser (CVE-2006-1614) and David Luyer discovered |
40 |
that ClamAV can be tricked into performing an invalid memory access |
41 |
(CVE-2006-1630). |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
By sending a malicious attachment to a mail server running ClamAV, a |
47 |
remote attacker could cause a Denial of Service or the execution of |
48 |
arbitrary code. Note that the overflow in the PE header parser is only |
49 |
exploitable when the ArchiveMaxFileSize option is disabled. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All ClamAV users should upgrade to the latest version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.88.1" |
63 |
