Description

The gnu.java.security.util.PRNG class in GNU Classpath 0.97.2 and earlier uses a predictable seed based on the system time, which makes it easier for context-dependent attackers to conduct brute force attacks against cryptographic routines that use this class for randomness, as demonstrated against DSA private keys.

Affected products

• GNU Classpath: through 0.97.2; 0.6, 0.7, 0.8, 0.9, 0.10, 0.11 (+18)
