(Oracle Issues Fix for Oracle Linux) Mozilla Firefox Integer Overflow in createImageBitmap() Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1038062
SecurityTracker URL:  http://securitytracker.com/id/1038062
CVE Reference:   CVE-2017-5428   (Links to External Site)
Date:  Mar 19 2017
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 52.0; possibly prior versions
Description:   A vulnerability was reported in Mozilla Firefox. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create specially crafted content that, when loaded by the target user, will trigger an integer overflow in the createImageBitmap() function and execute arbitrary code on the target user's system. The code will run in the content sandbox. As a result, a separate vulnerability must be exploited in conjunction with this vulnerability to gain privileges on the target user's system.

Chaitin Security Research Lab (via Trend Micro's Zero Day Initiative at Pwn2Own) reported this vulnerability.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.
Solution:   Oracle has issued a fix.
