Libcupsfilters: cups-filters: libcupsfilters: cpu exhaustion via infinite loop in cfieee1284normalizemakemodel()
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 ex…

Libcupsfilters: cups-filters: libcupsfilters: cups image filter process abort via malformed png
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 a…
