USN-3773-1: Ghostscript vulnerabilities

Releases

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

Packages

• ghostscript - PostScript and PDF interpreter

Details

It was discovered that Ghostscript contained multiple security issues. If a
user or automated system were tricked into processing a specially crafted
file, a remote attacker could possibly use these issues to access arbitrary
files, execute arbitrary code, or cause a denial of service.

Update instructions

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

Ubuntu 18.04

• ghostscript - 9.25~dfsg+1-0ubuntu0.18.04.1
• libgs9 - 9.25~dfsg+1-0ubuntu0.18.04.1

Ubuntu 16.04

• ghostscript - 9.25~dfsg+1-0ubuntu0.16.04.1
• libgs9 - 9.25~dfsg+1-0ubuntu0.16.04.1

Ubuntu 14.04

• ghostscript - 9.25~dfsg+1-0ubuntu0.14.04.1
• libgs9 - 9.25~dfsg+1-0ubuntu0.14.04.1

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
