Description

This security bulletin contains information about 1 security vulnerability.


1) Improper input validation (CVE-ID: CVE-2007-1497)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

nf_conntrack in netfilter in the Linux kernel before 2.6.20.3 does not set nfctinfo during reassembly of fragmented packets, which leaves the default value as IP_CT_ESTABLISHED and might allow remote attackers to bypass certain rulesets using IPv6 fragments.
