SSH is intended to replace rlogin and rsh, and to provide secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. OpenSSH is OpenBSD's version of the last free version of SSH, bringing it up to date in terms of security and features. This package includes the core files necessary for both the OpenSSH client and server. To make this package useful, you should also install openssh-clients, openssh-server, or both. -------------------------------------------------------------------------------- Update Information: CVE-2026-59996: Fix remote glob result of ".." causing files to be placed in unintended parent directories when scp performs remote-to-remote copy via the local host CVE-2026-60002: Fix use-after-free in cached hostkey during key re-exchange -------------------------------------------------------------------------------- ChangeLog: * Fri Jul 17 2026 Zoltan Fridrich - 10.0p1-11 - CVE-2026-59996: Fix remote glob result of ".." causing files to be placed in unintended parent directories when scp performs remote-to-remote copy via the local host Resolves: rhbz#2498027 - CVE-2026-60002: Fix use-after-free in cached hostkey during key re-exchange Resolves: rhbz#2497966 -------------------------------------------------------------------------------- References: [ 1 ] Bug #2497966 - CVE-2026-60002 openssh: OpenSSH: Use-after-free vulnerability during host key re-exchange on the client side [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=2497966 [ 2 ] Bug #2498027 - CVE-2026-59996 openssh: OpenSSH: `scp` file misplacement vulnerability during remote copy [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=2498027 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
