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"
