CVE-2023-5981 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gnutls, Linux 2024-01-10 N/A 5.9 MEDIUM
A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding.
CVE-2018-16868 1 Gnu 1 Gnutls 2020-12-04 3.3 LOW 5.6 MEDIUM
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.
CVE-2018-10846 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2020-10-22 1.9 LOW 5.6 MEDIUM
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.
CVE-2018-10845 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2020-10-22 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2018-10844 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2020-10-22 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2015-8313 2 Debian, Gnu 2 Debian Linux, Gnutls 2020-01-09 4.3 MEDIUM 5.9 MEDIUM
GnuTLS incorrectly validates the first byte of padding in CBC modes
