An anonymous reader writes "Just a few days after it was discovered, Symantec has posted a fix to a critical flaw with its Antivirus software." From the article: "The eEye digital security firm reported the problem initially, and discovered it was present in the newest versions of the affected Symantec products. Further research noted by Symantec described the problem as a flaw that made the products vulnerable to a stack overflow. Once exploited, that overflow could have permitted an attacker to execute code on the machine, with System level rights. The issue was made worse by being one that impacted enterprise-level customers, big spenders that purchase hundreds or thousands of licenses depending on the size of the business. "
