Description

This security bulletin contains information about 1 security vulnerability.


1) Loop with unreachable exit condition ('infinite loop') (CVE-ID: CVE-2004-0626)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The tcp_find_option function of the netfilter subsystem in Linux kernel 2.6, when using iptables and TCP options rules, allows remote attackers to cause a denial of service (CPU consumption by infinite loop) via a large option length that produces a negative integer after a casting operation to the char type.
