RHBA-2009:1668 - 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.
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 sshd, the SSH daemon, used multiple SFTP channels simultaneously, each SFTP cthannel leaked a UNIX socket. This leak could eventually cause sshd to consume large amounts of system resources. This update fixes the leak by ensuring that every SFTP channel closes the UNIX socket, with the result that using SFTP with multiple simultaneous channels does not cause sshd to monopolize system resources. (BZ#537348)
All users of openssh are advised to upgrade to these updated packages, which resolve this issue.
Solution
Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
