Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 26 Sep 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: evidence found.
1 Metasploit module
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 10 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

This update for cups-filters fixes the following issues: Changes in cups-filters: - CVE-2026-64611: Fixed Infinite-loop CPU-exhaustion DoS in cfIEEE1284NormalizeMakeModel on empty MDL field. A user who controls an IEEE-1284 device ID consumed by `cfIEEE1284GetMakeModel` can drive `cfIEEE1284NormalizeMakeModel` into an infinite loop. (bsc#1273145,GHSA-rcq7-rv5g-j3r4) - CVE-2026-64612: Fixed Malformed PNG aborts CUPS image filter process (missing libpng setjmp recovery) A authenticated client that can submit an image print job can abort the CUPS filter process by supplying a malformed PNG. (bsc#1273146,GHSA-7mxj-cfq5-84ch) - Provide cups-browsed as separated cups-filters-cups-browsed sub-package so users can uninstall this sub-package to completely avoid the generic security risk of cups-browsed. cups-browsed auto-creates local print queues for printers which are announced via DNS-SD. It is a generic security risk when a service (cups-browsed.service) accepts any (possibly malicious) incoming information from any host in the local network (i.e. any DNS-SD announcements) and from that information it auto-creates print queue configurations for CUPS (where its server program cupsd runs as root). For more information see the openSUSE support database article https://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings - Fixed a regression "Error about PPD file during 'driverless' printer setup" (boo#1256868) and "ppd pull out from [driverless] printer feature broken" (bsc#1256977) - unbreak qpdf [bsc#1253678] - CVE-2024-47176: Fixed cups-browsed binds to UDP INADDR_ANY:631 (bsc#1230939) and to avoid CVE-2024-47850 "cups-browsed can be abused to initiate remote DDoS against third-party targets" (bsc#1231294) by removing legacy CUPS Browsing support in cups-browsed (introduced 2012) which is no longer needed nowadays. CUPS browsing was removed from CUPS since version 1.6. Legacy CUPS Browsing is a generic security risk, see the section "Automated print queue setup via cups-browsed" in https://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings - CVE-2024-47076: Fixed lack of input sanitization in cfGetPrinterAttributes5 (bsc#1230937) - CVE-2024-47175: Fixed lack of input sanitization in _ppdCreateFromIPP() (bsc#1230932) - In general regarding CUPS and cups-browsed security issues see https://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings
