SecurityTracker Alert ID:  1015263
SecurityTracker URL:  http://securitytracker.com/id/1015263
CVE Reference:   CVE-2005-0664   (Links to External Site)
Updated:  Jun 13 2007
Original Entry Date:  Nov 24 2005
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes

Description:   A buffer overflow vulnerability was reported in libexif. A remote user may be able to cause a target user's application to crash or execute arbitrary code.

The exif library does not properly validate user-supplied input in several places. A remote user can create a specially crafted JPEG image with invalid EXIF header data. When the image is loaded by the target user's application that uses libexif, the application may crash or potentially execute arbitrary code.

The flaw resides in 'exif-data.c'.

Sylvain Defresne discovered this vulnerability.

Impact:   A remote user can create an image file that, when loaded by the target user's application, will cause the application to crash or potentially execute arbitrary code.
Solution:   Sun has issued the following fixes:

SPARC Platform

* Solaris 10 without patch 121095-01

x86 Platform
