uncertain whether this error is potentially exploitable, however, we
prefer to see bugs fixed proactively.' There have also been reports of
an exploit in the wild.

MandrakeSoft encourages all users to upgrade to these patched openssh
packages immediately and to disable sshd until you are able to upgrade
if at all possible.

Update :

The OpenSSH developers discovered more, similar, problems and revised
the patch to correct these issues. These new packages have the latest
patch fix applied."

"Updated OpenSSH packages are now available that fix bugs that may be
remotely exploitable.

[Updated 17 Sep 2003] Updated packages are now available to fix
additional buffer manipulation problems which were fixed in OpenSSH
3.7.1. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2003-0695 to these
additional issues.

We have also included fixes from Solar Designer for some additional
memory bugs. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2003-0682 to these issues.

OpenSSH is a suite of network connectivity tools that can be used to
establish encrypted connections between systems on a network and can
provide interactive login sessions and port forwarding, among other
functions.

The OpenSSH team has announced a bug which affects the OpenSSH buffer
handling code. This bug has the potential of being remotely
exploitable. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2003-0693 to this issue.

All users of OpenSSH should immediately apply this update which
contains a backported fix for this issue."
