USN-5075-1: Ghostscript vulnerability

Releases

• Ubuntu 21.04
• Ubuntu 20.04 LTS

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.

Update instructions

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

Ubuntu 21.04

• ghostscript - 9.53.3~dfsg-7ubuntu0.1
• libgs9 - 9.53.3~dfsg-7ubuntu0.1

Ubuntu 20.04

• ghostscript - 9.50~dfsg-5ubuntu4.3
• libgs9 - 9.50~dfsg-5ubuntu4.3

In general, a standard system update will make all the necessary changes.
