Gentoo Linux Security Advisory

Title: l2tpd: Buffer overflow (GLSA 200407-17)
Severity: high
Exploitable: remote
Date: July 22, 2004
Bug(s): #53009
ID: 200407-17

Synopsis


A buffer overflow in l2tpd could lead to remote code execution. It is not
known whether this bug is exploitable.


Background


l2tpd is a GPL implentation of the Layer 2 Tunneling Protocol.


Affected Packages

Package: net-dialup/l2tpd
Vulnerable: < 0.69-r2
Unaffected: >= 0.69-r2
Architectures: All supported architectures


Description


Thomas Walpuski discovered a buffer overflow that may be exploitable by
sending a specially crafted packet. In order to exploit the vulnerable
code, an attacker would need to fake the establishment of an L2TP tunnel.


Impact


A remote attacker may be able to execute arbitrary code with the privileges
of the user running l2tpd.


Workaround


There is no known workaround for this vulnerability.


Resolution


All users are recommended to upgrade to the latest stable version:
Code:
# emerge sync

    # emerge -pv ">=net-l2tpd-0.69-r2"
    # emerge ">=net-l2tpd-0.69-r2"
