CVE/CAN name
Vendor threat level Important
SophosLabs threat level Critical
Solution MS12-067
Vendor description This security update resolves publicly disclosed vulnerabilities in Microsoft FAST Search Server 2010 for SharePoint. The vulnerabilities could allow remote code execution in the security context of a user account with a restricted token. FAST Search Server for SharePoint is only affected by this issue when Advanced Filter Pack is enabled. By default, Advanced Filter Pack is disabled.
SophosLabs comments This publicly disclosed remote code execution vulnerability exists due to various ways in which the Oracle Outside In libraries (used by the Advanced Filter Pack) parse specially crafted files. However, to exploit this vulnerability, the attacker would need to have write access rights to a file location (in order to upload a specially crafted exploited file to said location) that is being used as FAST Search 2010 for SharePoint indexes. Although the vulnerability was publicly disclosed, neither Microsoft nor Sophoslabs have received any reports that these vulnerabilities had been used to attack customers at present. Nevertheless, SophosLabs strongly encourage users to update as quickly as possible.
