USN-4686-1: Ghostscript vulnerabilities

07 January 2021

Several security issues were fixed in Ghostscript.




It was discovered that Ghostscript incorrectly handled certain image
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.

Update instructions

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

Ubuntu 18.04
Ubuntu 16.04

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