Title: FreeBSD IPFW Me Point To Point Interface Address Addition Vulnerability
Severity: LOW
Description:
FreeBSD is a freely available BSD-based UNIX Operating System distributed and maintained by the FreeBSD Project.
A problem in the ipfw software package included with FreeBSD could allow unintended hosts on the other side of point to point interfaces access to the system.
The problem is in the handling of point to point interfaces and the use of the "me" identifier in ipfw rules. When a rule is added using the "me" identifier on a point to point interface, the ipfw arbitrarily allows access from the IP address on the remote end of the point to point link.
This problem could give unintended access to a system from a remote host, and could lead to potential compromise of local resources.
Affected Products:
- FreeBSD FreeBSD 4.3.0 -RELEASE
- FreeBSD FreeBSD 4.3.0 -STABLE
