Details

Richard Hughes discovered that gcab incorrectly handled certain malformed
cabinet files. If a user or automated system were tricked into opening a
specially crafted cabinet file, a remote attacker could use this issue to
cause gcab to crash, resulting in a denial of service, or possibly execute
arbitrary code.
