Sophos Anti Virus

Multiple Sophos Anti-Virus products, including Anti-Virus for Windows 5.x before 5.2.1 and 4.x before 4.05, when cabinet file inspection is enabled, allows remote attackers to execute arbitrary code via a CAB file with "invalid folder count values," which leads to heap corruption.Show less

Multiple interpretation error in Sophos 3.91 with the 2.28.4 engine allows remote attackers to bypass virus scanning via a file such as BAT, HTML, and EML with an "MZ" magic byte sequence which is normally associated with EXE, which causes the file to be treated as a safe type that could still be executed as a dangerous file type by applications on the end system, as demonstrated by a "triple headed" program that contains EXE, EML, and HTML content, aka the "magic byte bug."Show less

Multiple interpretation error in unspecified versions of Sophos Antivirus allows remote attackers to bypass virus detection via a malicious executable in a specially crafted RAR file with malformed central and local headers, which can still be opened by products such as Winrar and PowerZip, even though they are rejected as corrupted by Winzip and BitZipper.Show less
