Debian DSA-1788-1 : quagga - improper assertion

medium Nessus Plugin ID 38690

Synopsis

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

Description

It was discovered that Quagga, an IP routing daemon, could no longer process the Internet routing table due to broken handling of multiple 4-byte AS numbers in an AS path. If such a prefix is received, the BGP daemon crashes with an assert failure, leading to a denial of service.

Solution

Upgrade the quagga package.

The old stable distribution (etch) is not affected by this issue.

For the stable distribution (lenny), this problem has been fixed in version 0.99.10-1lenny2.
