Name of the Vulnerable Software and Affected Versions
GnuTLS library versions prior to 1.2.1
Description
The issue allows remote attackers to bypass the certificate revocation list (CRL) check and cause a stack-based buffer overflow via a crafted X.509 certificate. This is related to the extraction of a serial number. The vulnerability can be exploited remotely and may lead to a violation of confidentiality, integrity, and availability of protected information.
Recommendations
For versions prior to 1.2.1, update to version 1.2.1 or later to resolve the issue. As a temporary workaround, consider restricting the use of the
gnutls x509 crt get serial function until a patch is available. Avoid using crafted X.509 certificates in the affected library until the issue is resolved.Exploit
