MICROSOFT: On March 4, 2002, Microsoft released the first version of bulletin MS02-013.asp. On March 18, 2002, Microsoft re-released this bulletin to make customers aware of an additional vulnerability that is eliminated by the updated VM (Microsoft VM build 3805). Customers who have previously installed the new build do not need to take any additional action. ZLIB: A warning about the security flaw identified last week in the zlib compression/decompression library affecting Linux systems has been broadened to include Windows and any other operating systems that use the zlib code. In an update about the flaw on their Web site, it is explained that the code is used in far more programs than they originally believed. Affected applications on the site include Microsoft's DirectX 8, FrontPage, GDI+, Internet Explorer, Office, NetShow, Train Simulator, Visual Studio, and Windows Messenger. Also, Netscape Navigator, Network Associates' PGP security software, Symantec's Norton Antivirus, and Jasc Software's PaintShop Pro are affected. VIRUSES/WORMS: TROJ_JUNTADOR.B is compiled in Delphi, and is capable of sending ICQ messages. It drops files in the Windows directory and the System directory. It drops two backdoor programs, detected as BKDR_PSYCHWARD.F and BKDR_OBLIVION.B1. ******************************************** RECOMMENDATIONS ******************************************** For the HP vulnerability, obtain and install the latest release of the Java Web Start product.
