clamav vulnerabilities

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

  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS

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

Software Description

  • clamav - Anti-virus utility for Unix


It was discovered that ClamAV incorrectly handled certain malformed files. A remote attacker could use this issue to cause ClamAV to crash, resulting in a denial of service, or possibly execute arbitrary code.

In the default installation, attackers would be isolated by the ClamAV AppArmor profile.
