<p>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.

<description>
|
|
<p>A buffer overflow can be triggered within TestDisk when a malicious disk
|
|
image is attempting to be recovered.

|
<impact type="normal">
|
|
<p>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>
|
|
<p>There is no known workaround at this time.</p>

</workaround>

<resolution>
|
|
<p>All TestDisk users should upgrade to the latest version:</p>

<code>
|

# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-admin/testdisk-7.0-r2"
