Description

This security bulletin contains information about 1 vulnerability.


1) Security restrictions bypass (CVE-ID: CVE-2006-4572)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

ip6_tables in netfilter in the Linux kernel before 2.6.16.31 allows remote attackers to (1) bypass a rule that disallows a protocol, via a packet with the protocol header not located immediately after the fragment header, aka 'ip6_tables protocol bypass bug;' and (2) bypass a rule that looks for a certain extension header, via a packet with an extension header outside the first fragment, aka 'ip6_tables extension header bypass bug.'
