Ubuntu Security Notice USN-3789-1
October 11, 2018

clamav vulnerability
==========================================================================

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

- - Ubuntu 18.04 LTS
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS

Summary:

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

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

Details:

It was discovered that ClamAV incorrectly handled unpacking MEW
executables. A remote attacker could possibly use this issue to 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 18.04 LTS:
  clamav                          0.100.2+dfsg-1ubuntu0.18.04.1

Ubuntu 16.04 LTS:
  clamav                          0.100.2+dfsg-1ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  clamav                          0.100.2+dfsg-1ubuntu0.14.04.1

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
