Vetor base

AV:N/AC:M/Au:N/C:P/I:P/A:N

Name of the Vulnerable Software and Affected Versions GnuTLS versions prior to 2.7.6

Description The issue allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new certificates. This occurs when the GNUTLS VERIFY ALLOW X509 V1 CA CRT flag is not enabled, causing version 1 X.509 certificates to be treated as intermediate CAs.

Recommendations For versions prior to 2.7.6, update to version 2.7.6 or later to resolve the issue.
