Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
