Package : pgpdump
Type    : denial of service
Remote  : Yes
Link    : https://wiki.archlinux.org/index.php/CVE

Summary
=======

The package pgpdump before version 0.30-1 is vulnerable to denial of
service.

Resolution
==========

Upgrade to 0.30-1.

# pacman -Syu "pgpdump>=0.30-1"

The problem has been fixed upstream in version 0.30.

Workaround

None.

Description
===========

When pgpdump is run on specially crafted input, a denial of service
condition occurs. The program runs with 100% CPU usage for an indefinite
amount of time.
This can be abused in scenarios where users can supply input to pgpdump,
e.g. in http://www.pgpdump.net/.

Impact
======

A remote attacker is able to create a specially crafted input that is
leading to CPU resource consumption resulting in denial of service.
