** DISPUTED ** M2Crypto does not properly check the return value from the OpenSSL EVP_VerifyFinal, DSA_verify, ECDSA_verify, DSA_do_verify, and ECDSA_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. NOTE: a Linux vendor disputes the relevance of this report to the M2Crypto product because "these functions are not used anywhere in m2crypto."


may not be an issue, see redhat bug
debian: "m2crypto provides a direct mapping of the OpenSSL
functions, no incorrect call sites are known, if such are found
they should be fixed in the respective"
marking this as ignored
