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.

Affected products

macOS: through 10.8.5; 10.8.0, 10.8.1, 10.8.2, 10.8.3, 10.8.4, 10.8.5
