Working feverishly through the holiday weekend, Symantec's security response team <A HREF="http://www.eweek.com/article2/0,1895,1968603,00.asp?kc=ewnws053006dtx1k0000599">has completed patches</A> for a "high-risk" worm hole in two enterprise-facing product lines. The flaw, which could allow malicious hackers to take complete control of a system without any user action, was discovered and reported by eEye Digital Security. In an advisory posted May 27, Symantec described the issue as a stack overflow affecting the Symantec Client Security and Symantec AntiVirus Corporate Edition, two product suites targeted toward business and government customers.
