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.
