Authorization Bypass

gnutls is vulnerable to authorization bypass attacks. The vulnerability exists as GnuTLS before 2.7.6, when the GNUTLSVERIFYALLOWX509V1CACRT flag is not enabled, treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a...

Man-in-the-Middle (MitM)

gnutls is vulnerable to man-in-the-middle MitM attacks. The vulnerability exists as lib/x509/verify.c in GnuTLS before 3.1.22 and 3.2.x before 3.2.12 does not properly handle unspecified errors when verifying X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof...

Denial Of Service (DoS)

GnuTLS is vulnerable to denial of service. A buffer over-read occurs in the gnutlsciphertext2compressed function in lib/gnutlscipher.c when CBC-mode cipher suites are used. This allows a remote attacker to crash the process via a crafted padding length...

Remote Code Execution (RCE)

gnutls is vulnerable to remote code execution RCE attacks. The vulnerability exists due to a possible buffer overflow in the readserverhello function in lib/gnutlshandshake.c in GnuTLS before 3.1.25, 3.2.x before 3.2.15, and 3.3.x before 3.3.4 allows remote servers to cause a denial of service...

Denial Of Service (DoS)

gnutls is vulnerable to denial of service DoS attacks. The vulnerability exists as the gnutlsx509oid2macalgorithm function in lib/gnutlsalgorithms.c allows remote attackers to cause a denial of service through a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS,...
