clamav vulnerabilities
==========================================================================

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

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

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

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

Details:

It was discovered that ClamAV would incorrectly parse a UPX-packed
executable, leading to possible inappropriate heap reads. An attacker
could use this issue to cause ClamAV to crash, resulting in a denial of
service, or possibly execute arbitrary code. (CVE-2013-2020)

It was discovered that ClamAV would incorrectly parse a PDF document,
potentially writing beyond the size of a static array. An attacker could
use this issue to cause ClamAV to crash, resulting in a denial of service,
or possibly execute arbitrary code. (CVE-2013-2021)

Update instructions:

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

Ubuntu 13.04:
  clamav                          0.97.8+dfsg-1ubuntu1.13.04.1

Ubuntu 12.10:
  clamav                          0.97.8+dfsg-1ubuntu1.12.10.1

Ubuntu 12.04 LTS:
  clamav                          0.97.8+dfsg-1ubuntu1.12.04.1

Ubuntu 11.10:
  clamav                          0.97.8+dfsg-1ubuntu1.11.10.1

Ubuntu 10.04 LTS:
  clamav                          0.97.8+dfsg-1ubuntu1.10.04.1

This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart ClamAV to
make all the necessary changes.
