Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
