Description

1) Out-of-bounds read (CVE-ID: CVE-2019-11598)
The vulnerability allows a remote attacker to access sensitive information or cause a denial of service (DoS) condition.
The vulnerability exists due to a boundary condition in the "WritePNMImage()" function in the "coders/pnm.c" file. A remote attacker can send a specially crafted image file (related to SetGrayscaleImage in MagickCore/quantize.c.), trick the victim into opening it, trigger out-of-bounds read error, get access to sensitive information or cause a DoS condition on the targeted system.
