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)
