-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-a80275b42d 2026-07-09 00:54:37.609381+00:00 -------------------------------------------------------------------------------- Name : openssh Product : Fedora 44 Version : 10.2p1 Release : 12.fc44 URL : http://www.openssh.com/portable.html Summary : An open source implementation of SSH protocol version 2 Description : SSH (Secure SHell) is a program for logging into and executing commands on a remote machine. 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: Improve GSS KEX algorithms documentation CVE-2026-55653: Fix double free in openssh DH-GEX client path during FIPS known- group validation that leads to client-side denial of service CVE-2026-55654: Fix heap out-of-bounds read during GSSAPI indicator cleanup due to missing NULL terminator CVE-2026-55655: Fix MITM of X11 forwarding via abstract UNIX socket pre-binding -------------------------------------------------------------------------------- ChangeLog: * Tue Jul 7 2026 Dmitry Belyavskiy <dbelyavs@redhat.com> - 10.2p1-12 - Improve GSS KEX algorithms documentation Patches are submitted by xspielinbox+redhat@protonmail.com Resolves: rhbz#2241564 * Tue Jul 7 2026 Zoltan Fridrich <zfridric@redhat.com> - 10.2p1-11 - CVE-2026-55653: Fix double free in openssh DH-GEX client path during FIPS known-group validation that leads to client-side denial of service - CVE-2026-55654: Fix heap out-of-bounds read during GSSAPI indicator cleanup due to missing NULL terminator - CVE-2026-55655: Fix MITM of X11 forwarding via abstract UNIX socket pre-binding - Remove duplicate manpage entries from ssh(1) Resolves: rhbz#2442505 -------------------------------------------------------------------------------- References: [ 1 ] Bug #2241564 - KexAlgorithms accepts gss-* algorithms in certain cases, but it is completely unclear what this does https://bugzilla.redhat.com/show_bug.cgi?id=2241564 [ 2 ] Bug #2442505 - 0043-openssh-8.7p1-ssh-manpage.patch introduces duplicates in documentation https://bugzilla.redhat.com/show_bug.cgi?id=2442505 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
