Denial-of-Service (DoS) Vulnerability

A Denial-of-Service vulnerability was discovered in the F-Secure Atlant and in certain WithSecure products while scanning fuzzed PE32-bit files it is possible that can crash the scanning engine. The exploit can be triggered remotely by an attacker.

F-Secure Anti-Virus for Linux Gateways 4.65 allows remote attackers to cause a denial of service (possibly fatal scan error), and possibly bypass virus detection, by inserting invalid characters into base64 encoded content in a multipart/mixed MIME file, as demonstrated with the EICAR test file.

The fsmsh.dll host module in F-Secure Policy Manager Server 7.00 and earlier allows remote attackers to cause a denial of service (application crash) via NTFS reserved words in filenames in URLs.

Unspecified vulnerability in multiple F-Secure anti-virus products, including Internet Security 2006 through 2008, Anti-Virus 2006 through 2008, and others, allows remote attackers to execute arbitrary code or cause a denial of service (hang or crash) via a malformed archive that triggers an unhandled exception, as demonstrated by the PROTOS GENOME test suite for Archive Formats.

F-Secure Anti-Virus for Windows Servers 7.0 64-bit edition allows local users to bypass virus scanning by using the system32 directory to store a crafted (1) archive or (2) packed executable. NOTE: in many environments, this does not cross privilege boundaries because any process able to write to system32 could also shut off F-Secure Anti-Virus.

Format string vulnerability in F-Secure Anti-Virus Client Security 6.02 allows local users to cause a denial of service and possibly gain privileges via format string specifiers in the Management Server name field on the Communication settings page.

Multiple F-Secure anti-virus products for Microsoft Windows and Linux before 20070619 allow remote attackers to bypass scanning via a crafted header in a (1) LHA or (2) RAR archive.

Multiple F-Secure anti-virus products for Microsoft Windows and Linux before 20070522 allow remote attackers to cause a denial of service (file scanning infinite loop) via certain crafted (1) ARJ archives or (2) FSG packed files.

Multiple F-Secure anti-virus products, including Internet Security 2006 through 2008, Anti-Virus 2006 through 2008, F-Secure Protection Service, and others, allow remote attackers to bypass malware detection via a crafted CAB archive.

Multiple F-Secure anti-virus products, including Internet Security 2006 through 2008, Anti-Virus 2006 through 2008, F-Secure Protection Service, and others, allow remote attackers to bypass malware detection via a crafted RAR archive. NOTE: this might be related to CVE-2008-0792.

Multiple F-Secure anti-virus products, including Anti-Virus for Microsoft Exchange 7.10 and earlier; Internet Gatekeeper for Windows 6.61 and earlier, Windows 6.61 and earlier, and Linux 2.16 and earlier; Internet Security 2009 and earlier, Anti-Virus 2009 and earlier, Client Security 8.0 and earlier, and others; allow remote attackers to bypass malware detection via a crafted (1) ZIP and (2) RAR archive.

Integer overflow in multiple F-Secure anti-virus products, including Internet Security 2006 through 2008, Anti-Virus 2006 through 2008, and others, when configured to scan inside compressed archives, allows remote attackers to execute arbitrary code via a crafted RPM compressed archive file, which triggers a buffer overflow.

Buffer overflow in the LHA decompression component in F-Secure anti-virus products for Microsoft Windows and Linux before 20070529 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted LHA archive, related to an integer wrap, a similar issue to CVE-2006-4335.

Unspecified vulnerability in the Real-time Scanning component in multiple F-Secure products, including Internet Security 2005, 2006 and 2007; Anti-Virus 2005, 2006 and 2007; and Solutions based on F-Secure Protection Service for Consumers 6.40 and earlier allows local users to gain privileges via a crafted I/O request packet (IRP), related to IOCTL (Input/Output Control) and "access validation of the address space."

F-Secure Anti-Virus 5.41 and 5.42 on Windows, Client Security 5.50 and 5.52, 4.60 for Samba Servers, and 4.52 and earlier for Linux does not properly detect certain viruses in a PKZip archive, which allows viruses such as Sober.D and Sober.G to bypass initial detection.

F-Secure Anti-Virus for Microsoft Exchange 6.30 and 6.31 does not properly detect certain password-protected files in a ZIP file, which allows remote attackers to bypass anti-virus protection.

Multiple content security gateway and antivirus products allow remote attackers to bypass content restrictions via MIME messages that use RFC2231 encoding, which may be interpreted differently by mail clients.

Unknown vulnerability in F-Secure Anti-Virus (FSAV) 4.52 for Linux before Hotfix 3 allows the Sober.D worm to bypass FASV.

The Management Agent in F-Secure Policy Manager 5.11.2810 allows remote attackers to gain sensitive information, such as the absolute path for the web server, via an HTTP request to fsmsh.dll without any parameters.

Multiple content security gateway and antivirus products allow remote attackers to bypass content restrictions via MIME messages that use fields that use RFC2047 encoding, which may be interpreted differently by mail clients.
