Title:	zoo: Buffer overflow
Date:	03/16/2006
Bugs:	#125622
ID:	200603-12

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	Architecture(s)
app-arch/zoo	< 2.10-r2	>= 2.10-r2	All supported architectures

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"
