Synopsis
=======

ProZilla contains several buffer overflow vulnerabilities that can be exploited by a malicious server to execute arbitrary code with the rights of the user running ProZilla.

Background
=========

ProZilla is a download accelerator for Linux.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/prozilla <= 1.3.6-r2 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers.

Description
==========

ProZilla contains several exploitable buffer overflows in the code handling the network protocols.

Impact
=====

A remote attacker could setup a malicious server and entice a user to retrieve files from that server using ProZilla. This could lead to the execution of arbitrary code with the rights of the user running ProZilla.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

Currently, there is no released version of ProZilla that contains a fix for these issues. The original author did not respond to our queries, the code contains several other problems and more secure alternatives exist. Therefore, the ProZilla package has been hard-masked prior to complete removal from Portage, and current users are advised to unmerge the package.

Availability
===========

This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
