On June 28, details of multiple critical vulnerabilities in Symantec and Norton branded antivirus products were released. Some of the vulnerabilities include wormable remote code execution flaws as the administrative or system user.
Simply receiving an email with a file or receiving a link to an exploit is enough to allow your system to be compromised. No interaction is necessary to trigger the exploit. This vulnerability is also wormable, which means that it could be turned into a computer worm.
