Description:Summary:
Gentoo Linux Local Security Checks GLSA 201408-14

Vulnerability Insight:
stunnel does not properly update the state of the pseudo-random generator after fork-threading which causes subsequent children with the same process ID to use the same entropy pool. ECDSA and DSA keys, when not used in deterministic mode (RFC6979), rely on random data for its k parameter to not leak private key information.

Solution:
Update the affected packages to the latest available version.

CVSS Score:
4.3
