GnuTLS 信息泄露漏洞

GnuTLS is an open-source, free security communication library developed by GnuTLS that enables the implementation of SSL, TLS, and DTLS protocols. There is a security vulnerability in gnutls, which stems from the fact that the PKCS7 padding check does not occur at a constant time during decryptio...

gnutls: gnutls: Security bypass due to incorrect name constraint handling

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...

The vulnerability of the compare_strings() function in the GnuTLS library allows a malicious actor to gain unauthorized access to protected information.

The vulnerability of the comparestrings function in the GnuTLS library is related to shortcomings in the mechanism for handling register-dependent data. Exploiting this vulnerability could allow an attacker to gain unauthorized access to protected information...

Astra Linux – Vulnerability in gnutls28

A vulnerability was identified: the response times for malformed ciphertexts in RSA-PSK ClientKeyExchange differ from those of ciphertexts with correct PKCS1 v1.5 padding...

Undefined Behavior for Input to API

Overview Affected versions of this package are vulnerable to Undefined Behavior for Input to API in the comparator function responsible for ordering Datagram Transport Layer Security DTLS packets by sequence numbers. An attacker can cause unstable packet ordering or undefined behavior by sending...

EUVD-2026-28386

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation via incorrect handling of name constraints during certificate validation. An attacker can bypass critical certificate validation checks by presenting a certificate chain where permitted name constraints a...

EUVD-2026-28354

A flaw was found in gnutls. Servers configured with RSA-PSK Rivest–Shamir–Adleman – Pre-Shared Key wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass...
