USN-3915-1: Ghostscript vulnerabilities

Releases

• Ubuntu 18.10
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM

Packages

• ghostscript - PostScript and PDF interpreter

Details

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

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.10

• ghostscript - 9.26~dfsg+0-0ubuntu0.18.10.8

• ghostscript - 9.26~dfsg+0-0ubuntu0.14.04.8
