F-secure » Internet Gatekeeper » 6.50 : Security Vulnerabilities, CVEs,

A Denial-of-Service (DoS) vulnerability was discovered in F-Secure Linux Security whereby the Fmlib component used in certain F-Secure products can crash while scanning fuzzed files. The exploit can be triggered remotely by an attacker. A successful attack will result in Denial-of-Service of the Anti-Virus engine.

A vulnerability affecting F-Secure antivirus engine before Capricorn update 2022-02-01_01 was discovered whereby decompression of ACE file causes the scanner service to stop. The vulnerability can be exploited remotely by an attacker. A successful attack will result in denial-of-service of the antivirus engine.

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.

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."

Buffer overflow in the web console in F-Secure Anti-Virus for Microsoft Exchange 6.40, and Internet Gatekeeper 6.40 through 6.42 and 6.50 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown attack vectors. NOTE: By default, the connections are only allowed from the local host.
