Security update for cups-filters

This update for cups-filters fixes the following issues:

  • CVE-2026-64611: user who controls an IEEE-1284 device ID consumed by cfIEEE1284GetMakeModel can drive cfIEEE1284NormalizeMakeModel into an infinite loop (bsc#1273145).
  • CVE-2026-64612: authenticated client that can submit an image print job can abort the CUPS filter process by supplying a malformed PNG (bsc#1273146).

Описание

A flaw was found in libcupsfilters. The cfIEEE1284NormalizeMakeModel() function enters an infinite loop when processing a printer-advertised IEEE-1284 device ID with an empty model field, causing sustained CPU consumption. A network-adjacent attacker could exploit this by broadcasting a specially crafted printer advertisement, leading to denial of service.

Описание

A flaw was found in libcupsfilters and cups-filters. The PNG image reading function creates a libpng reader without installing an error recovery handler, causing the CUPS image filter process to abort when processing a malformed PNG file. An unauthenticated attacker could exploit this by submitting a specially crafted PNG print job, leading to denial of service of the in-flight print job.
