Summary

The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack.

Exploit prediction (EPSS)

1.24% probability of exploitation in the next 30 days, higher than 69% of all scored CVEs.
