Synopsis
========

A buffer overflow in TestDisk might allow remote attackers to execute
arbitrary code.

Background
==========

TestDisk is powerful free data recovery software! It was primarily
designed to help recover lost partitions and/or make non-booting disks
bootable again when these symptoms are caused by faulty software:
certain types of viruses or human error (such as accidentally deleting
a Partition Table). Partition table recovery using TestDisk is really
easy.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/testdisk < 7.0-r2 >= 7.0-r2

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

A buffer overflow can be triggered within TestDisk when a malicious
disk image is attempting to be recovered.

Impact
======

A remote attacker could coerce the victim to run TestDisk against their
malicious image. This may be leveraged by an attacker to crash
TestDisk and gain control of program execution.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All TestDisk users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/testdisk-7.0"
