MS06-049 Causing Silent Data Corruption

Posted by ryuzaki0 on from the oh-who-wants-encryption-anyway dept.

Uncle Mike writes "It looks like there is a problem with the recently released MS06-049 / KB920958 patch. If you have compression activated on any folder, then the compressed data is at risk from corruption. New files that are close to a multiple of 4K in size will have their last 4,000 bytes or so overwritten with 0xDF. Although this problem has been reported to Microsoft, as yet there appears to have been no official announcement. "

  1. Has anyone seen this problem? by antdude · · Score: 0, Redundant

    I use compression on folders in XP Pro. and Home SP2. I have not seen this problem on my systems at home and work. I always get the newest patches on their first release dates. I even defragged (PerfectDisk v6.0 with its patches) over the weekend. I haven't seen anything odd. I am using old IDE and SATA HDDs.
