CVE-2009-0127
Published: 15 January 2009
** 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."

mdeslaur | 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 |
