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 N/A
2017-08-08 CVE-2016-4456 The "GNUTLS_KEYLOGFILE" environment variable in gnutls 3.4.12 allows remote attackers to overwrite and corrupt arbitrary files in the filesystem. Gnutls N/A
2020-01-27 CVE-2015-0294 GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate. Debian_linux, Gnutls, Enterprise_linux N/A
2019-12-20 CVE-2015-8313 GnuTLS incorrectly validates the first byte of padding in CBC modes Debian_linux, Gnutls N/A
2009-11-09 CVE-2009-3555 The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions,... Http_server, Ubuntu_linux, Debian_linux, Fedora, Gnutls, Internet_information_server, Nss, Openssl N/A
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
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
2018-12-03 CVE-2018-16868 A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS#1 v1.5 data. An attacker who is able to run process on the same physical core as the victim process, could use this to extract plaintext or in some cases downgrade any TLS connections to a vulnerable server. Gnutls 5.6
2018-08-22 CVE-2018-10846 A cache-based side channel in GnuTLS implementation that leads to plain text recovery in cross-VM attack setting was found. An attacker could use a combination of "Just in Time" Prime+probe attack in combination with Lucky-13 attack to recover plain text using crafted packets. Debian_linux, Gnutls, Ansible_tower, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation 5.6
2018-08-22 CVE-2018-10845 It was found that the GnuTLS implementation of HMAC-SHA-384 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets. Debian_linux, Gnutls, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation 5.9
