Sources and claim methodology

Upstream source description

A flaw was found in Ghostscript. A remote attacker could exploit this vulnerability by enticing a user to process a specially crafted PDF or PostScript document containing malicious mesh shading data. Due to improper bounds validation during the processing of indexed color values, Ghostscript triggers an out-of-bounds memory read. Successful exploitation can lead to a Denial of Service (DoS) through an application crash or result in limited information disclosure.
