The patch, MS06-042, appears to break other software and causes Internet Explorer to crash, according to Microsoft's security website and other IT forums. A number of IT administrators on security mailing lists are complaining that the patch causes some PeopleSoft web-based applications to crash.
Microsoft's security site has been updated to let customers know that if they are applying the security patch for Internet Explorer 6 Service Pack 1 systems, the web browser may crash while certain sites are being viewed.
While the re-release isn't expected until August 22, Microsoft does have a temporary fix for the problem, but users must call the company's support line to get it.
The company still recommends that the current patch be applied because it addresses eight security flaws in the browser, although Microsoft's technical help desk recommends that users disable the use of HTTP 1.1 in the browser's advanced settings menu.
The patch for Internet Explorer was one of 12 that Microsoft issued last Tuesday, with MS06-040 being singled out as the most important one to install. MS06-040 is a remotely exploitable buffer overrun flaw in the Windows Server service. Attackers have already started to exploit the flaw.
Patch glitches are nothing new for IT administrators. In April, a second patch for Windows Internet Explorer had to be issued by Microsoft because the first one caused problems with Nvidia drivers and Hewlett-Packard software. In June, one of the company's patches caused network problems for users.
