{"id":"SUSE-SU-2025:20160-1","summary":"Security update for openssh","details":"This update for openssh fixes the following issues:\n\n- CVE-2025-26465: Fixed MitM attack against OpenSSH's VerifyHostKeyDNS-enabled client (bsc#1237040).\n- CVE-2025-26466: Fixed DoS attack against OpenSSH's client and server (bsc#1237041).\n\nOther bugfixes:\n\n- Fix ssh client segfault with GSSAPIKeyExchange=yes in ssh_kex2 due to gssapi proposal not being correctly initialized (bsc#1236826). \n- Add #include \u003cstdlib.h\u003e in some files added by the ldap patch to fix build with gcc14 (bsc#1225904).\n- Added missing struct initializer, added missing parameter (bsc#1222840).\n- Remove OPENSSL_HAVE_EVPGCM-ifdef, which is no longer supported by upstream (bsc#1221928). \n- Use %config(noreplace) for sshd_config. In any case, it's recommended to drop a file in sshd_config.d instead of editing sshd_config (bsc#1221063).\n- Add a patch to fix a regression introduced in 9.6 that makes X11 forwarding very slow (bsc#1229449).\n- Drop keycat binary that is not supported, except of the code that is used by other SELinux patches (bsc#1229072).\n- Fix RFC4256 implementation that keyboard-interactive authentication method can send instructions and sshd shows them to users (bsc#1229010).\n- Add attempts to mitigate instances of secrets lingering in memory after a session exits (bsc#1186673, bsc#1213004, bsc#1213008).\n- Remove empty line at the end of sshd-sle.pamd (bsc#1227456)\n","modified":"2026-03-11T07:29:41.700398Z","published":"2025-03-25T09:02:20Z","related":["CVE-2025-26465","CVE-2025-26466"],"upstream":["CVE-2025-26465","CVE-2025-26466"],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2025/suse-su-202520160-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1186673"},{"type":"REPORT","url":"https://bugzilla.suse.com/1213004"},{"type":"REPORT","url":"https://bugzilla.suse.com/1213008"},{"type":"REPORT","url":"https://bugzilla.suse.com/1221063"},{"type":"REPORT","url":"https://bugzilla.suse.com/1221928"},{"type":"REPORT","url":"https://bugzilla.suse.com/1222840"},{"type":"REPORT","url":"https://bugzilla.suse.com/1225904"},{"type":"REPORT","url":"https://bugzilla.suse.com/1227456"},{"type":"REPORT","url":"https://bugzilla.suse.com/1229010"},{"type":"REPORT","url":"https://bugzilla.suse.com/1229072"},{"type":"REPORT","url":"https://bugzilla.suse.com/1229449"},{"type":"REPORT","url":"https://bugzilla.suse.com/1236826"},{"type":"REPORT","url":"https://bugzilla.suse.com/1237040"},{"type":"REPORT","url":"https://bugzilla.suse.com/1237041"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2025-26465"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2025-26466"}],"affected":[{"package":{"name":"openssh","ecosystem":"SUSE:Linux Micro 6.0","purl":"pkg:rpm/suse/openssh&distro=SUSE%20Linux%20Micro%206.0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.6p1-3.1"}]}],"ecosystem_specific":{"binaries":[{"openssh-clients":"9.6p1-3.1","openssh-common":"9.6p1-3.1","openssh-fips":"9.6p1-3.1","openssh-server-config-rootlogin":"9.6p1-3.1","openssh-server":"9.6p1-3.1","openssh":"9.6p1-3.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2025:20160-1.json"}}],"schema_version":"1.7.5"}
