NVD Description

Note: Versions mentioned in the description apply only to the upstream gnutls-utils package and not the gnutls-utils package as distributed by Oracle. See How to fix? for Oracle:10 relevant fixed versions and status.

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. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
