RHBA-2011:0848 - openssh bug fix update


Synopsis

openssh bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated openssh packages that fix a bug are now available for Red Hat Enterprise Linux 6.

Description

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

This update fixes the following bug:

  • Previously, when the SSH_USE_STRONG_RNG variable was set to 1, openssh read 48 bytes from the /dev/random number generator to generate a seed. This seed was too long and caused long delays on ssh or sshd startup and when connections were received. Now, the SSH_USE_STRONG_RNG variable contains number of bytes that should be pulled from /dev/random (with a minimum default value of six) and the delays no longer occur. (BZ#708924)

All openssh users are advised to upgrade to these updated packages, which fix this bug.

Solution

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

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
