Synopsis
========
A buffer overflow in zoo may be exploited to execute arbitrary when
creating archives of specially crafted directories and files.
Background
==========
zoo is a file archiving utility for maintaining collections of files,
written by Rahul Dhesi.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/zoo < 2.10-r2 >= 2.10-r2
Description
===========
zoo is vulnerable to a new buffer overflow due to insecure use of the
strcpy() function when trying to create an archive from certain
directories or filenames.
Impact
======
An attacker could exploit this issue by enticing a user to create a zoo
archive of specially crafted directories and filenames, possibly
leading to the execution of arbitrary code with the rights of the user
running zoo.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All zoo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r2"
