SecurityTracker URL: http://securitytracker.com/id/1014055
|
|
CVE Reference:
CAN-2005-0605
(Links to External Site)
|
Date: May 26 2005
|
Impact:
Execution of arbitrary code via network, User access via network
|
Fix Available: Yes Vendor Confirmed: Yes
|
|
Description:
An integer overflow vulnerability was reported in libXpm. A remote user may be able to cause arbitrary code to be executed. LessTif is affected.
The 'lib/scan.c' code does not properly validate user-supplied data contained in image files. A remote user can create a specially crafted image file that, when processed by the target user or application, will trigger the overflow and execute arbitrary code.
Negative values in the 'image->bitmap_unit' variable can trigger the overflow.
|
Impact:
A remote user can create an image that, when processed by libXpm, will execute arbitrary code on the target system.
|
Solution:
Red Hat has released a fix.
