Last month, Microsoft released the security patch for MS06-049, which addresses a vulnerability in the Windows kernel allowing privilege escalation that could enable any logged on user to gain complete control over the affected system. Just a month after its release however, some users have claimed to experience some problems with the security patch.
When the patch is applied to a system with folders that have the compression option enabled, the compressed data residing within those folders is at risk from corruption. Newly created files having a particular file size (approximately a multiple of 4K) may have their last 4000 bytes overwritten.
This problem has already been reported to
Microsoft but there is no official announcement from them yet. One of the possible workarounds for preventing the problem caused by this patch is to disable folder compression. We’ll update you once a word about this problem has been sent out.
