Threats Tagged 'cve-2026-64611'

Libcupsfilters provides a library, which implements common functions used in cups-browsed daemon and printing filters, and additional files as banner templates and character sets. The filters are used in CUPS daemon and in printer applications. Security Fix(es): * libcupsfilters: cups-filters: libcupsfilters: CPU exhaustion via infinite loop in cfIEEE1284NormalizeMakeModel() (CVE-2026-64611) * libcupsfilters: cups-filters: libcupsfilters: CUPS image filter process abort via malformed PNG (CVE-2026-64612) For 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.

A vulnerability in libcupsfilters causes the cfIEEE1284NormalizeMakeModel() function to enter an infinite loop when processing a printer-advertised IEEE-1284 device ID with an empty model field. This results in sustained CPU consumption and can be exploited by a network-adjacent attacker broadcasting a crafted printer advertisement, leading to denial of service. The issue affects Red Hat Enterprise Linux 10 and related variants. The cups-browsed service, which uses this component, is disabled by default in RHEL, reducing exposure. A security update addressing this flaw is available from Red Hat.
