In versions 2.4.16 and prior, in a network-exposed cupsd with a shared target queue, an unauthorized client can send a Print-Job to that shared PostScript queue without authentication. The server accepts a page-border value supplied as textWithoutLanguage, preserves an embedded newline through option escaping and reparse, and then reparses the resulting second-line PPD: text as a trusted scheduler control record. A follow-up raw print job can therefore make the server execute an attacker-chosen existing binary such as /usr/bin/vim as lp.

In versions 2.4.16 and prior, a use-after-free vulnerability exists in the CUPS scheduler (cupsd) when temporary printers are automatically deleted. cupsdDeleteTemporaryPrinters() in scheduler/printers.c calls cupsdDeletePrinter() without first expiring subscriptions that reference the printer, leaving cupsd_subscription_t.dest as a dangling pointer to freed heap memory. The dangling pointer is subsequently dereferenced at multiple code sites, causing a crash (denial of service) of the cupsd daemon. With heap grooming, this can be leveraged for code execution.(CVE-2026-39316)","status":"published","published":"2026-04-25T11:11:01Z","modified":"2026-08-18T01:19:48.548276771Z","cvss":[{"version":"3.1","score":6.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","level":"medium"}],"updated_at":"2026-11-02T15:52:46.087701Z"},{"id":"RHSA-2026:36733","title":"Red Hat Security Advisory: cups security update","status":"published","published":"2026-07-09T10:12:49Z","modified":"2026-09-02T10:16:13Z","cvss":[{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L","level":"medium"}],"updated_at":"2026-11-02T15:53:19.963895Z"},{"id":"RHSA-2026:39302","title":"Red Hat Security Advisory: cups security update","status":"published","published":"2026-07-15T10:10:16Z","modified":"2026-09-02T10:16:54Z","cvss":[{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L","level":"medium"}],"updated_at":"2026-11-02T15:53:20.491441Z"},{"id":"RHSA-2026:39316","title":"Red Hat Security Advisory: cups security update","status":"published","published":"2026-07-15T10:10:19Z","modified":"2026-09-02T10:16:56Z","cvss":[{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L","level":"medium"}],"updated_at":"2026-11-02T15:53:20.491441Z"},{"id":"RHSA-2026:8814","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","status":"published","published":"2026-04-20T10:12:14Z","modified":"2026-10-14T10:33:09Z","cvss":[{"version":"3.1","score":8,"vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:23.547034Z"},{"id":"RLSA-2026:36733","title":"Moderate: cups security update","description":"The Common UNIX Printing System (CUPS) provides a portable printing layer for Linux, UNIX, and similar operating systems.\n\nSecurity Fix(es):\n\n* cups: OpenPrinting CUPS: Shared PostScript queue lets anonymous Print-Job requests reach `lp` code execution over the network (CVE-2026-34980)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.","status":"published","published":"2026-07-09T06:00:16.850158Z","modified":"2026-07-09T06:30:04.131102899Z","cvss":[{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L","level":"medium"}],"updated_at":"2026-11-02T15:53:25.804165Z"},{"id":"RLSA-2026:39302","title":"Moderate: cups security update","description":"The Common UNIX Printing System (CUPS) provides a portable printing layer for Linux, UNIX, and similar operating systems.\n\nSecurity Fix(es):\n\n* cups: OpenPrinting CUPS: Shared PostScript queue lets anonymous Print-Job requests reach `lp` code execution over the network (CVE-2026-34980)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.","status":"published","published":"2026-07-15T12:06:01.640959Z","modified":"2026-07-15T12:30:06.230384264Z","cvss":[{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L","level":"medium"}],"updated_at":"2026-11-02T15:53:26.111232Z"},{"id":"RLSA-2026:39316","title":"Moderate: cups security update","description":"The Common UNIX Printing System (CUPS) provides a portable printing layer for Linux, UNIX, and similar operating systems.\n\nSecurity Fix(es):\n\n* cups: OpenPrinting CUPS: Shared PostScript queue lets anonymous Print-Job requests reach `lp` code execution over the network (CVE-2026-34980)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.","status":"published","published":"2026-07-15T12:03:43.176942Z","modified":"2026-07-15T12:30:04.923165846Z","cvss":[{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L","level":"medium"}],"updated_at":"2026-11-02T15:53:26.111232Z"},{"id":"ROOT-OS-DEBIAN-12-CVE-2026-34980","title":"CVE-2026-34980 in cups - Patched by Root","description":"Root has patched CVE-2026-34980 in the cups package for Root:Debian:12.
