USN-5224-1: Ghostscript vulnerabilities

12 January 2022

Several security issues were fixed in Ghostscript.




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
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 21.10
Ubuntu 21.04
Ubuntu 20.04
Ubuntu 18.04

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