gnutls: gnutls: Security bypass allows acceptance of revoked server certificates via crafted OCSP response

A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol OCSP response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabl...

gnutls: gnutls: Use-after-free in gnutls_pkcs11_token_set_pin

A flaw was found in GnuTLS. The gnutlspkcs11tokensetpin function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path...

gnutls: GnuTLS: Denial of Service via heap buffer overflow in DTLS handshake fragment reassembly

A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in mergehandshakepacket where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the messagelength field remains...

gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...
