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.

Security readout for executives and security teams

This is a side-channel weakness in OpenSSL DSA signing. On affected versions, timing differences could help a local user recover a DSA private key. It is not a remote-code-execution issue, and the supplied sources do not show active exploitation, but private-key exposure can be business-critical where DSA keys protect trust. Exposure is most likely on systems or bundled products using OpenSSL through 1.0.2h and performing DSA signing. Risk is higher where untrusted local users can execute code or observe timing on the same host. Downstream products may be affected through embedded OpenSSL. Handle through normal vulnerability remediation unless DSA private keys protect sensitive authentication, signing, or compliance workflows. Escalate priority for shared systems with untrusted local access or products confirmed affected by vendor advisories. Mitigation focus: Apply vendor-provided OpenSSL security updates for affected platforms and bundled products.; Review OpenSSL advisories and downstream vendor bulletins before choosing exact fixed packages.; Prioritize systems holding DSA private keys or allowing untrusted local users..
