F5 Networks BIG-IP : GnuTLS RSA PKCS signature vulnerability (K17327)

medium Nessus Plugin ID 86187


The remote device is missing a vendor-supplied security patch.


GnuTLS before 3.1.0 does not verify that the RSA PKCS #1 signature algorithm matches the signature algorithm in the certificate, which allows remote attackers to conduct downgrade attacks via unspecified vectors. (CVE-2015-0282)


Upgrade to one of the non-vulnerable versions listed in the F5 Solution K17327.
