(Debian Issues Fix) Apache mod_auth_radius radcpy() Integer Overflow Lets Remote Users Deny Service in Certain Cases
SecurityTracker Alert ID:  1013031
SecurityTracker URL:  http://securitytracker.com/id/1013031
CVE Reference:   CVE-2005-0108   (Links to External Site)
Date:  Jan 28 2005
Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 1.5.7
Description:   An integer overflow vulnerability was reported in Apache mod_auth_radius. A remote user with the ability to monitor and spoof RADIUS packets can cause the target service to crash.

LSS reported that the software copies data based on a user-supplied 'length' value. If a remote user can monitor RADIUS packets and the remote user can spoof RADIUS packets, the remote user can send a specially crafted RADIUS_ACCESS_CHALLENGE to trigger the integer overflow.

The vulnerability resides in 'mod_auth_radius.c' in the radcpy() function.

Leon Juranic is credited with discovering this flaw.

The original advisory is available at:

http://security.lss.hr/en/index.php?page=details&ID=LSS-2005-01-02

Impact:   A remote user can cause the target service to crash.
Solution:   Debian has released a fix for the stable distribution (woody) in version 1.3.14-1.3 and for the unstable distribution (sid) in version 1.3.16-3.

Debian GNU/Linux 3.0 alias woody:

Package        : libpam-radius-auth
Vulnerability  : information leak, integer underflow
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-1340 CAN-2005-0108

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:

CAN-2004-1340

    The Debian package accidently 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.

CAN-2005-0108

    Leon Juranic discoverd 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.


Upgrade Instructions
- --------------------
