Kurt Seifried discovered that ClamAV incorrectly handled certain JavaScript files. An attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2013-6497)
Damien Millescamp discovered that ClamAV incorrectly handled certain PE files. An attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2014-9050).
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.
