Exiv2 is a C++ library and set of tools for parsing, editing and saving
|
||
|
|
Exif and IPTC 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 an integer overflow
|
||
|
|
vulnerability in the JpegThumbnail::setDataArea() method leading to a
|
||
|
|
heap-based buffer overflow.

An attacker could entice the user of an application making use of Exiv2
|
||
|
|
or an application included in Exiv2 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.
|
||
|

|
||

</impact>
|

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