CVE-2013-5180 Information

Description

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.
