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.
