AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a heap-buffer-overread in GnuTLS that occurs when handling the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. A malicious user can craft a certificate with a malformed SCT extension that causes GnuTLS to expose sensitive data during certificate verification.
How can this vulnerability impact me? :
The vulnerability can lead to the exposure of confidential information when GnuTLS verifies certificates from certain websites. This means that sensitive data could be leaked to an attacker if a malformed SCT extension is encountered.
