CentOS developers, Could someone take a look at this? It was posted on the CentOS Forum by bdaniels. Apparently this security update came out on May 1, but not all versions have been made available for CentOS. Akemi === Forum posting by bdaniels === Well, the announce list has been posting them: [CentOS-announce] CESA-2007:0257 Low CentOS 4 s390(x) openssh - security update 05/04/2007 06:44 PM CentOS Errata and Security Advisory 2007:0257 https://rhn.redhat.com/errata/RHSA-2007-0257.html But only for the s390 and ia64 architectures. The i386/ia32 ones are missing.
