SUSE CVE-2019-15523

An issue was discovered in LINBIT csync2 through 2.0. It does not correctly check for the return value GNUTLSEWARNINGALERTRECEIVED of the gnutlshandshake function. It neglects to call this function again, as required by the design of the API...

SUSE CVE-2020-11501

GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 2018-07-16 because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks...

OpenConnect 8.09 has a buffer overflow, causing a denial of service application crash or possibly unspecified other impact, via crafted certificate data to getcertname in gnutls.c...

SUSE CVE-2020-13777

GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3. The earliest affected version is 3.6.4 2018-09-24 because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS...

SUSE CVE-2020-14154

Mutt before 1.14.3 proceeds with a connection even if, in response to a GnuTLS certificate prompt, the user rejects an expired intermediate certificate...

SUSE CVE-2020-24659

An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a norenegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the...

SUSE CVE-2021-20232

A flaw was found in gnutls. A use after free issue in clientsendparams in lib/ext/presharedkey.c may lead to memory corruption and other potential consequences...

SUSE CVE-2021-20231

A flaw was found in gnutls. A use after free issue in client sending keyshare extension may lead to memory corruption and other consequences...

SUSE CVE-2022-2509

A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutlspkcs7verify function...

SUSE CVE-2023-0361

A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to...

CVE-2023-0361

CVE-2023-0361 describes a timing side-channel in GnuTLS during RSA ClientKeyExchange handling that can enable Bleichenbacher-style attacks to recover the RSA key and decrypt accompanying application data. The vulnerability affects GnuTLS implementations across multiple advisories and distribution...
