Internet Security Systems has found <A HREF="http://news.zdnet.com/2100-1009_22-5589439.html?tag=zdnn.alert">a flaw in Trend Micro's virus scanning software</A>--the third time this month that the security company has picked a hole in an antivirus product. The vulnerability affects Trend Micro's Antivirus Library, a common set of code used by at least 29 Trend Micro products, according to separate advisories posted on Trend Micro's Web site on Wednesday and on ISS' site on Thursday. An attacker could create a program that exploits the security hole, causing the antivirus program to run a virus instead of blocking the malicious program, the companies said.
