{"id":"CVE-2009-0127","details":"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.","modified":"2026-04-10T03:40:32.686305Z","published":"2009-01-15T17:30:00Z","database_specific":{"isDisputed":true},"references":[{"type":"ADVISORY","url":"http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=511515"},{"type":"ARTICLE","url":"http://openwall.com/lists/oss-security/2009/01/12/4"},{"type":"EVIDENCE","url":"https://bugzilla.redhat.com/show_bug.cgi?id=479676"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=479676"}],"schema_version":"1.7.5"}
