Microsoft has acknowledged problems caused by a patch released this week that can cause system errors.
Dustin Childs, group manager of response communications at Microsoft Trustworthy Computing, said in an update that users may be experiencing difficulties after applying security update 2823324, which it provided in security bulletin MS13-036 on Tuesday.
He said: “We've determined that the update, when paired with certain third-party software, can cause system errors. As a precaution, we stopped pushing 2823324 as an update when we began investigating the error reports, and have since removed it from the download centre.”
However he denied that the system errors result in any data loss or affect all Windows customers, and recommended following guidance to uninstall the update if it is already installed.
The announcement came after claims were made that the update can crash a system, or cause a ‘blue screen of death'. According to Winbeta the update results in an infinite reboot loop, while a blog by Woody Leonhard said that the update is causing blue screens on machines running Windows 7.
He said: “So far the problem is widely reported in Brazil, and at least one other credible sighting has occurred in South Africa and one in the UK - but it isn't clear if they were running the Brazilian version of Windows. Apparently the patch corrupts ntfs.sys. One fix that's been floated is to copy ntfs.sys from a good machine (same version of Windows) to a bluescreened machine.”
The moderate-level patch was released to address a vulnerability that requires an attacker to have physical computer access to exploit.
