<p>
|
|
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a
|
|
stack based buffer overflow in the libTIFF library when reading a TIFF
|
|
image with a malformed BitsPerSample tag.
|
|
</p>
|
|

|
|
<impact type="normal">
|
|
<p>
|
|
Successful exploitation would require the victim to open a specially
|
|
crafted TIFF image, resulting in the execution of arbitrary code.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

<p>
|
|
All libTIFF users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/tiff-3.7.2"</code>
