Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2013-5172)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The kernel in Apple Mac OS X before 10.9 does not properly determine the output length for SHA-2 digest function calls, which allows context-dependent attackers to cause a denial of service (panic) by triggering a digest operation, as demonstrated by an IPSec connection.
