Technical Description
NOTE: this issue has been disputed by the upstream vendor. nasl/nasl_crypto2.c in the Nessus Attack Scripting Language library (aka libnasl) 2.2.11 does not properly check the return value from the OpenSSL DSA_do_verify function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077. NOTE: the upstream vendor has disputed this issue, stating "while we do misuse this function (this is a bug), it has absolutely no security ramification.
Remediation
Check the references section for vendor advisories and patches from finkproject. Update libnasl to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
