CVE-2020-16305

A buffer overflow vulnerability in pcx_write_rle() in contrib/japanese/gdev10v.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A buffer overflow vulnerability in pcx_write_rle() in contrib/japanese/gdev10v.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed.

The following packages have been upgraded to a later upstream version: ghostscript (9.27). (BZ#1874523)

These are all security issues fixed in the ghostscript-9.56.1-5.1 package on the GA media of openSUSE Tumbleweed.

It was discovered that Ghostscript incorrectly handled certain document files. If a user or automated system were tricked into processing a specially crafted file, a remote attacker could use this issue to cause Ghostscript to crash, resulting in a denial of service, or possibly execute arbitrary code.
