ZDI-08-033: Motorola RAZR JPG Processing Stack Overflow Vulnerability
May 27, 2008

- -- Affected Vendors:

- -- Affected Products:
Motorola RAZR

- -- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable Motorola RAZR firmware based cell phones. User interaction is
required to exploit this vulnerability in that the target must accept a
malicious image sent via MMS.

The specific flaw exists in the JPEG thumbprint component of the EXIF
parser. A corrupt JPEG received via MMS can cause a memory corruption
which can be leveraged to execute arbitrary code on the affected device.

- -- Vendor Response:
Motorola states:
Together, ZDI and Motorola have identified a potential vulnerability
related to viewing malicious, manipulated JPEG files affecting select
RAZR-series devices.   Although the possibility of this vulnerability
occurring is very remote and would only occur in unique circumstances,
Motorola proactively corrected it in all new device releases.
