CVE-2021-20232

CWE-416
 

 
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.

 
 
CVE-2021-20231

CVE-2020-13777

CWE-327
 

 
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.

CVE-2015-0294

CWE-295
 

 
GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate.

 
2019-12-20
 
CVE-2015-8313

CWE-203
 

 
GnuTLS incorrectly validates the first byte of padding in CBC modes

 
2019-04-01
 
CVE-2019-3836

CWE-824
 

 
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.

 
2019-03-27
 
CVE-2019-3829

CWE-416
 

 
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.

 
2018-12-03
 
CVE-2018-16868

CWE-310
 

 
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

CWE-327
 

 
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

CWE-327
 

 
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.
