username to be used for authentication is used as a format string when
writing a log message. This vulnerability may allow an attacker to
execute arbitrary code with the privileges of the program requesting
PAM authentication.
For the stable distribution (woody) this problem has been fixed in
version 0.5.2-3woody1.
