<title>tiff: New overflows in image decoding</title>
|
|
<synopsis>
|
|
An integer overflow has been found in the TIFF library image decoding
|
|
routines and the tiffdump utility, potentially allowing arbitrary code
|
|
execution.

The TIFF library contains encoding and decoding routines for the
|
|
Tag Image File Format. It is called by numerous programs, including
|
|
GNOME and KDE applications, to interpret TIFF images.

infamous41md found a potential integer overflow in the directory
|
|
entry count routines of the TIFF library (CAN-2004-1308). Dmitry V.
|
|
Levin found another similar issue in the tiffdump utility
|
|
(CAN-2004-1183).

<p>
|
|
A remote attacker could entice a user to view a carefully crafted
|
|
TIFF image file, which would potentially lead to execution of arbitrary
|
|
code with the rights of the user viewing the image. This affects any
|
|
program that makes use of the TIFF library, including many web browsers
|
|
or mail readers.
|
|
</p>

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

All TIFF library users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/tiff-3.7.1-r1"</code>
