2011-12-08 CVE-2011-4128 Buffer overflow in the gnutls_session_get_data function in lib/gnutls_session.c in GnuTLS 2.12.x before 2.12.14 and 3.x before 3.0.7, when used on a client that performs nonstandard session resumption, allows remote TLS servers to cause a denial of service (application crash) via a large SessionTicket. Gnutls N/A
2012-03-26 CVE-2012-1573 gnutls_cipher.c in libgnutls in GnuTLS before 2.12.17 and 3.x before 3.0.15 does not properly handle data encrypted with a block cipher, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) via a crafted record, as demonstrated by a crafted GenericBlockCipher structure. Gnutls N/A
2013-07-03 CVE-2013-2116 The _gnutls_ciphertext2compressed function in lib/gnutls_cipher.c in GnuTLS 2.12.23 allows remote attackers to cause a denial of service (buffer over-read and crash) via a crafted padding length. NOTE: this might be due to an incorrect fix for CVE-2013-0169. Gnutls N/A
2019-03-27 CVE-2019-3829 A vulnerability was found in gnutls versions from 3.5.8 before 3.6.7. A memory corruption (double free) vulnerability in the certificate verification API. Any client or server application that verifies X.509 certificates with GnuTLS 3.5.8 or later is affected. Fedora, Gnutls 7.5
2019-04-01 CVE-2019-3836 It was discovered in gnutls before version 3.6.7 upstream that there is an uninitialized pointer access in gnutls versions 3.6.3 or later which can be triggered by certain post-handshake messages. Fedora, Gnutls, Leap 7.5
2020-04-03 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 the security guarantees of the DTLS protocol. Ubuntu_linux, Debian_linux, Fedora, Gnutls, Leap 7.4
2020-06-04 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 server always uses wrong data in place of an encryption key derived from an application. Ubuntu_linux, Debian_linux, Fedora, Gnutls 7.4
2020-09-04 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 no_renegotiation 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 gnutls_deinit function is called after detecting a handshake failure. Ubuntu_linux, Fedora, Gnutls, Leap 7.5
2021-03-12 CVE-2021-20231 A flaw was found in gnutls. A use after free issue in client sending key_share extension may lead to memory corruption and other consequences. Fedora, Gnutls, Active_iq_unified_manager, E\-Series_performance_analyzer, Enterprise_linux 9.8
2021-03-12 CVE-2021-20232 A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences. Fedora, Gnutls, Enterprise_linux 9.8
