Name of the Vulnerable Software and Affected Versions GnuTLS versions prior to 3.4.15 GnuTLS versions 3.5.x prior to 3.5.4

Description The issue concerns the gnutls ocsp resp check crt function, which does not verify the serial length of an OCSP response. This could potentially allow remote attackers to bypass an intended certificate validation mechanism via vectors involving trailing bytes left by gnutls malloc.

Recommendations For GnuTLS versions prior to 3.4.15, update to version 3.4.15 or later. For GnuTLS versions 3.5.x prior to 3.5.4, update to version 3.5.4 or later.
