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.
Отчет
This Moderate denial-of-service flaw in libcupsfilters and cups-filters allows an unauthenticated attacker to crash the CUPS image filter process. By submitting a specially crafted PNG print job, an attacker can trigger an abort, impacting only the in-flight print job rather than the overall CUPS service stability.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
