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.

Multiple unspecified vulnerabilities in Sophos SAVScan 4.33.0 for Linux, and possibly other products and versions, allow remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via crafted files that have been packed with (1) armadillo, (2) asprotect, or (3) asprotectSKE.

Sophos Anti-Virus for Windows before 7.6.3, Anti-Virus for Windows NT/9x before 4.7.18, Anti-Virus for OS X before 4.9.18, Anti-Virus for Linux before 6.4.5, Anti-Virus for UNIX before 7.0.5, Anti-Virus for Unix and Netware before 4.37.0, Sophos EM Library, and Sophos small business solutions, when CAB archive scanning is enabled, allows remote attackers to cause a denial of service (segmentation fault) via a "fuzzed" CAB archive file, as demonstrated by the OUSPG PROTOS GENOME test suite for Archive Formats.

Sophos Anti-Virus 4.33.0, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.

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.

Sophos Anti-Virus 7.0.5, and other 7.x versions, when Runtime Behavioural Analysis is enabled, allows local users to cause a denial of service (reboot with the product disabled) and possibly gain privileges via a zero value in a certain length field in the ObjectAttributes argument to the NtCreateKey hooked System Service Descriptor Table (SSDT) function.

Multiple cross-site scripting (XSS) vulnerabilities in the web administration interface in Sophos ES1000 and ES4000 Email Security Appliance 2.1.0.0 allow remote attackers to inject arbitrary web script or HTML via the (1) error and (2) go parameters to the login page.

The virus detection engine in Sophos Anti-Virus before 2.49.0 does not properly process malformed (1) CAB, (2) LZH, and (3) RAR files with modified headers, which might allow remote attackers to bypass malware detection.

Cross-site scripting (XSS) vulnerability in Sophos Anti-Virus for Windows 6.x before 6.5.8 and 7.x before 7.0.1 allows remote attackers to inject arbitrary web script or HTML via an archive with a file that matches a virus signature and has a crafted filename that is not properly handled by the print function in SavMain.exe.

Sophos Anti-Virus for Windows and for Unix/Linux before 2.48.0 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted UPX packed file, resulting from an "integer cast around". NOTE: as of 20070828, the vendor says this is a DoS and the researcher says this allows code execution, but the researcher is reliable.
