A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5961-1 - It was discovered that abcm2ps incorrectly handled memory when parsing specially crafted ABC files.
