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.
3.6.5-2ubuntu1
Affected by 5 other vulnerabilities.

Aliases:
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.

CVE-2020-24659
GNUTLS-SA-2020-09-04
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.
3.6.13-2ubuntu1.3
Affected by 2 other vulnerabilities.

Aliases:
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.
3.6.5-2ubuntu1
Affected by 5 other vulnerabilities.

Aliases:
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.
3.6.13-2ubuntu1.6
Affected by 0 other vulnerabilities.
VCID-e5m6-uzg2-aaaj
Aliases:
CVE-2020-13777
GNUTLS-SA-2020-06-03
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.
3.6.9-5ubuntu1.2
Affected by 3 other vulnerabilities.
3.6.13-2ubuntu1.1
Affected by 3 other vulnerabilities.
VCID-f9sc-4new-aaad
Aliases:
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.
3.6.5-2ubuntu1
Affected by 5 other vulnerabilities.
VCID-x6hd-tczu-aaaf
Aliases:
CVE-2021-20232
GNUTLS-SA-2021-03-10
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.
