Two problems have been discovered in the libpam-radius-auth package, the PAM RADIUS authentication module. The Common Vulnerabilities and Exposures Project identifies the following problems:
The Debian package accidentally installed its configuration file /etc/pam_radius_auth.conf world-readable. Since it may possibly contain secrets all local users are able to read them if the administrator hasn't adjusted file permissions. This problem is Debian specific.
Leon Juranic discovered an integer underflow in the mod_auth_radius module for Apache which is also present in libpam-radius-auth.
For the stable distribution (woody) these problems have been fixed in version 1.3.14-1.3.
For the unstable distribution (sid) these problems have been fixed in version 1.3.16-3.
We recommend that you upgrade your libpam-radius-auth package.
