Vulnerability Spotlight: Symantec Norton Security IDSvix86 PE Remote System Denial of Service
Summary: Cisco Talos disclosed a denial of service vulnerability, CVE-2016-5308 / TALOS-2016-0182, in the Portable Executable file scanning functionality of Symantec Norton Security, discovered by Talos researcher Piotr Bania. A crafted PE file with a large SizeOfRawData field in a section header causes an access violation in the IDSvix86 kernel driver when the parser fails to check the value against the file's bounds, leading MD5Compress to access unavailable memory and crash the machine.
Bottom line: The trigger is an emailed file, so the crash lands on the endpoint running the security product itself - and Talos notes the flaw is detected only by sids 39466 and 39467.
