Vulnerability from fkie_nvd - Published: 2007-11-30 01:46 - Updated: 2026-06-16 22:47
Severity
Summary
The "internal state tracking" code for the random and urandom devices in FreeBSD 5.5, 6.1 through 6.3, and 7.0 beta 4 allows local users to obtain portions of previously-accessed random values, which could be leveraged to bypass protection mechanisms that rely on secrecy of those values.
