libcrypt-openssl-dsa-perl does not properly check the return value from the OpenSSL DSA_verify and DSA_do_verify functions, which might allow remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
