Cross-site scripting (XSS) vulnerability in Sophos PureMessage for UNIX before 6.3.2 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The installation of Sophos PureMessage for Microsoft Exchange 3.0 before 3.0.2, when both anti-virus and anti-spam are supported, does not create or launch the associated scan engines when the system is under heavy load, which has unspecified impact, probably remote bypass of scanner protection or a denial of service (message loss or delay).

Sophos PureMessage Scanner service (PMScanner.exe) in PureMessage for Microsoft Exchange 3.0 before 3.0.2 allows remote attackers to cause a denial of service (message queue delay and incomplete spam rule update) via a crafted (1) RTF or (2) PDF file.

Sophos PureMessage for Microsoft Exchange 3.0 before 3.0.2 allows remote attackers to cause a denial of service (EdgeTransport.exe termination) via a TNEF-encoded message with a crafted rich text body that is not properly handled during conversion to plain text. NOTE: this might be related to CVE-2008-7104.

Sophos virus detection engine 2.75 on Linux and Unix, as used in Sophos Email Appliance, Pure Message for Unix, and Sophos Anti-Virus Interface (SAVI), allows remote attackers to cause a denial of service (engine crash) via zero-length MIME attachments.
