exiftags is a library and set of tools for parsing, editing and saving
|
|
Exif metadata from images. Exif, the Exchangeable image file format,
|
|
specifies the addition of metadata tags to JPEG, TIFF and RIFF files.

|
|
Meder Kydyraliev (Google Security) discovered that Exif metadata is not
|
|
properly sanitized before being processed, resulting in illegal memory
|
|
access in the postprop() and other functions (CVE-2007-6354). He also
|
|
discovered integer overflow vulnerabilities in the parsetag() and other
|
|
functions (CVE-2007-6355) and an infinite recursion in the readifds()
|
|
function caused by recursive IFD references (CVE-2007-6356).

<impact type="normal">
|
|
<p>
|
|
An attacker could entice the user of an application making use of
|
|
exiftags or an application included in exiftags to load an image file
|
|
with specially crafted Exif tags, possibly resulting in the execution
|
|
of arbitrary code with the privileges of the user running the
|
|
application or a Denial of Service.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All exiftags users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-gfx/exiftags-1.01"</code>
|
