MS15-129: Security Update for Silverlight to Address Remote Code Execution (3106614) (Mac OS X)
High Nessus Plugin ID 87251
SynopsisA multimedia application framework installed on the remote Mac OS X host is affected by multiple vulnerabilities.
DescriptionThe version of Microsoft Silverlight installed on the remote Mac OS X host is affected by the following vulnerabilities :
- Multiple information disclosure vulnerabilities exist due to a failure to properly handle objects in memory.
An attacker can exploit these issues, via crafted Silverlight content, to more reliably predict pointer values and thus degrade the effectiveness of the Address Space Layout Randomization (ASLR) security feature, allowing the system to be further compromised.
- A remote code execution vulnerability exists due to incorrect handling of certain open and close requests, which result in read and write access violations. A remote attacker can exploit this vulnerability, via a specially crafted Silverlight application, to gain privileges and take complete control of the affected host. (CVE-2015-6166)
SolutionMicrosoft has released a set of patches for Silverlight 5.
