Debian-specific: no
CVE ID         : CVE-2006-2194

A bug has been discovered in several packages that execute teh
setuid() system call without checking for sucess when trying to drop
privileges, which may fail with some PAM configurations.

For the stable distribution (sarge) this problem has been fixed in
version 4.0.3-31sarge8.

For the unstable distribution (sid) this problem has been fixed in
version 4.0.17-2.

We recommend that you upgrade your passwd package.
