Details

It was discovered that Bind incorrectly handled GSSAPI security policy
negotiation. A remote attacker could use this issue to cause Bind to crash,
resulting in a denial of service, or possibly execute arbitrary code. In
the default installation, attackers would be isolated by the Bind AppArmor
profile.
