Name of the Vulnerable Software and Affected Versions OpenSSL versions 1.0.2h and earlier
Description The issue is related to the dsa sign setup function in OpenSSL, which does not ensure the use of constant-time operations. This makes it easier for local users to discover a DSA private key via a timing side-channel attack. The vulnerability can allow an attacker to recover the DSA private key under certain conditions, potentially affecting SSH servers that use DSA keys.
Recommendations For OpenSSL versions 1.0.2h and earlier, consider upgrading to a version that addresses this issue, as the current version does not properly ensure the use of constant-time operations, making it vulnerable to timing side-channel attacks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
