---|---|---|---|---|---|---|
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 | ||
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, Nginx, Fedora, Gnutls, Nss, Openssl | N/A | ||
2010-05-24 | CVE-2006-7239 | The _gnutls_x509_oid2mac_algorithm function in lib/gnutls_algorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service (crash) via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference. | Gnutls | N/A | ||
2015-08-14 | CVE-2014-8155 | GnuTLS before 2.9.10 does not verify the activation and expiration dates of CA certificates, which allows man-in-the-middle attackers to spoof servers via a certificate issued by a CA certificate that is (1) not yet valid or (2) no longer valid. | Gnutls | N/A | ||
2018-08-22 | CVE-2018-10844 | It was found that the GnuTLS implementation of HMAC-SHA-256 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data using crafted packets. | Ubuntu_linux, Debian_linux, Fedora, Gnutls, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation | 5.9 | ||
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. | Ubuntu_linux, Debian_linux, Fedora, Gnutls, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation | 5.9 | ||
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. | Ubuntu_linux, Debian_linux, Fedora, Gnutls, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation | 5.6 | ||
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 |
