RHBA-2011:1195 - openssh bug fix update

Synopsis

openssh bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated openssh packages that resolve an issue are now available for Red Hat Enterprise Linux 5.

Description

OpenSSH is OpenBSD's SSH (Secure Shell) protocol implementation. These packages include the core files necessary for both the OpenSSH client and server.

These updated openssh packages fix the following bug:

  • When Federal Information Processing Standards (FIPS) mode was enabled on a system, key-based authentication was always unsuccessful. This was caused by the newly introduced pubkey_key_verify() verification function, which did not take into consideration the fact that it was running in a FIPS environment. With this update, the pubkey_key_verify() function has been modified to respect FIPS, and authentication using an RSA key is now successful without any issues when FIPS mode is enabled. (BZ#730652)

All users of openssh are advised to upgrade to these updated packages, which resolve this issue.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
