Description
This security bulletin contains information about 1 security vulnerability.
1) Cryptographic issues (CVE-ID: CVE-2013-5180)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The srandomdev function in Libc in Apple Mac OS X before 10.9, when the kernel random-number generator is unavailable, produces predictable values instead of the intended random values, which makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms by leveraging knowledge of these values, related to a compiler-optimization issue.
