PACKAGE : openssh
SUMMARY : OpenSSH vulnerability
DATE : 2002-03-07 17:44:00

DESCRIPTION
OpenSSH is a very popular and versatile tool that uses encrypted
connections between hosts and is commonly used for remote
administration.
Joost Pol <[email protected]> discovered[1] a off-by-one bug in OpenSSH's
channel code that could be used by an attacker with a local account
on the victim's machine to obtain root privileges on that machine.
Another scenario for this vulnerability is that of a malicious ssh
server exploiting a vulnerable ssh client connecting to it.
SOLUTION
It is recommended that all OpenSSH users upgrade their packages. The
sshd service will be automatically restarted after the upgrade if it
was already running at that time.
