(CVE-2026-106553, CVE-2026-106555)\n\nIt was discovered that OpenSSH incorrectly used an LZ77 dictionary coder\nduring compression. An attacker could possibly use this issue to obtain\nsensitive information. (CVE-2026-106582)\n\nIt was discovered that OpenSSH's ssh client incorrectly allowed special\ncharacters in command-line usernames. An attacker could possibly use this\nissue to inject arbitrary commands via specially crafted usernames.\n(CVE-2026-106583)\n\nIt was discovered that OpenSSH's ssh-keygen incorrectly handled Daylight\nSaving Time when converting dates. An attacker could possibly use this\nissue to cause certificates to have incorrect expiration times.\n(CVE-2026-106584)\n\nIt was discovered that OpenSSH did not check whether the maximum packet\nlength was exceeded during decompression. A remote attacker could possibly\nuse this issue to cause a denial of service. (CVE-2026-106585)\n\nIt was discovered that OpenSSH's sshd server incorrectly applied the\nrestrict keyword from authorized_keys to tunnel forwarding requests. A\nlocal attacker with an authorized key could possibly use this issue to\nbypass intended tunnel forwarding restrictions. (CVE-2026-106586)\n\nIt was discovered that OpenSSH's sshd server incorrectly handled certain\nconfiguration options that accept a \"none\" value. An attacker could\npossibly use this issue to cause OpenSSH to behave unexpectedly.\n(CVE-2026-106587)","status":"published","published":"2026-10-19T13:34:39Z","modified":"2026-10-19T23:43:21.200850366Z","updated_at":"2026-11-02T16:58:26.907654Z"}]}}
