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.
