Ubuntu Security Notice USN-1258-1
November 10, 2011

clamav vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS


ClamAV could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:
- clamav: Anti-virus utility for Unix


Stephane Chazelas discovered the bytecode engine of ClamAV improperly
handled recursion under certain circumstances. This could allow a remote
attacker to craft a file that could cause ClamAV to crash, resulting in a
denial of service.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
  libclamav6                      0.97.3+dfsg-1ubuntu0.11.10.1

Ubuntu 11.04:
  libclamav6                      0.97.3+dfsg-1ubuntu0.11.04.1

Ubuntu 10.10:
  libclamav6                      0.96.5+dfsg-1ubuntu1.10.10.3

Ubuntu 10.04 LTS:
  libclamav6                      0.96.5+dfsg-1ubuntu1.10.04.3

In general, a standard system update will make all the necessary changes.
