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.
