<title>tiff: Buffer overflows in image decoding</title>
|
|
<synopsis>
|
|
Multiple heap-based overflows have been found in the tiff library image
|
|
decoding routines, potentially allowing to execute arbitrary code with the
|
|
rights of the user viewing a malicious image.

The tiff library contains encoding and decoding routines for the Tag Image
|
|
File Format. It is called by numerous programs, including GNOME and KDE, to
|
|
help in displaying TIFF images. xv is a multi-format image manipulation
|
|
utility that is statically linked to the tiff library.

Chris Evans found heap-based overflows in RLE decoding routines in
|
|
tif_next.c, tif_thunder.c and potentially tif_luv.c.

|
<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 GNOME and KDE web browsers or
|
|
mail readers.

<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 -pv ">=media-libs/tiff-3.6.1-r2"
|
|
# emerge ">=media-libs/tiff-3.6.1-r2"</code>
|
|
<p>
|
|
xv makes use of the tiff library and needs to be recompiled to receive the
|
|
new patched version of the library. All xv users should also upgrade to the
|
|
latest version:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=media-gfx/xv-3.10a-r8"
|
|
# emerge ">=media-gfx/xv-3.10a-r8"</code>
