Description

The authentication module for Apache 2.0.40 through 2.0.45 on Unix does not properly handle threads safely when using the crypt_r or crypt functions, which allows remote attackers to cause a denial of service (failed Basic authentication with valid usernames and passwords) when a threaded MPM is used.

Affected configurations

• apache http server 2.0.40 • apache http server 2.0.41 • apache http server 2.0.42 • apache http server 2.0.43 • apache http server 2.0.44 • apache http server 2.0.45
