Debian DSA-2546-1 : freeradius - stack-based buffer overflows

medium Nessus Plugin ID 62049

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Timo Warns discovered that the EAP-TLS handling of FreeRADIUS, a high-performance and highly configurable RADIUS server, is not properly performing length checks on user-supplied input before copying to a local stack buffer. As a result, an unauthenticated attacker can exploit this flaw to crash the daemon or execute arbitrary code via crafted certificates.

Solution

Upgrade the freeradius packages.

For the stable distribution (squeeze), this problem has been fixed in version 2.1.10+dfsg-2+squeeze1.
