CVE-2015-0282
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.
Does this matter?
Lower severity and a low EPSS score (1.40%). Track it; it rarely justifies an emergency change on its own.
