Microsoft has pulled one of the patches it released on Tuesday as part of its monthly security update.
MS13-061, which addresses three vulnerabilities in Exchange Server, was scrapped after Microsoft became aware that installing it causes problems. The issues do not occur in Exchange 2007 or 2010 environments, only 2013.
"Specifically, the content index for mailbox databases shows as 'failed' and the Microsoft Exchange Search Host Controller service is renamed," according to a blog post from Ross Smith, principal program manager of the Exchange Server product group.
The three bugs actually lie in the way Exchange files are processed by Oracle Outside In, a set of libraries that software developers use to decode hundreds of file formats.
For administrators that have already deployed the patch, Microsoft recommends they apply KB 2879739, a workaround described here. For those who have not yet installed the fix, the software giant suggests they do not and instead follow the simple Exploitable Vulnerabilities portion of the original security bulletin.
