WRQ Reflection for Secure IT Windows Server 6.0 (formerly known as F-Secure SSH server) processes access and deny lists in a case-sensitive manner, when previous versions were case-insensitive, which might allow remote attackers to bypass intended restrictions and login to accounts that should be denied.

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.

Multiple stack-based buffer overflows in the getheader function in header.c for LHA 1.14, as used in products such as Barracuda Spam Firewall, allow remote attackers or local users to execute arbitrary code via long directory or file names in an LHA archive, which triggers the overflow when testing or extracting the archive.

A vulnerability affecting F-Secure SAFE browser protection was discovered improper URL handling can be triggered to cause universal cross-site scripting through browsing protection in a SAFE web browser. User interaction is required prior to exploitation. A successful exploitation may lead to arbitrary code execution.

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.

An issue was discovered in F-Secure SAFE 17.7 on macOS. Due to incorrect client version verification, an attacker can connect to a privileged XPC service, and execute privileged commands on the system. NOTE: the attacker needs to execute code on an already compromised machine.

An issue was discovered in F-Secure SAFE 17.7 on macOS. The XPC services use the PID to identify the connecting client, which allows an attacker to perform a PID reuse attack and connect to a privileged XPC service, and execute privileged commands on the system. NOTE: the attacker needs to execute code on an already compromised machine.

A vulnerability was discovered in the web user interface of F-Secure Internet Gatekeeper. An authenticated user can modify settings through the web user interface in a way that could lead to an arbitrary code execution on the F-Secure Internet Gatekeeper server.

A vulnerability affecting F-Secure SAFE browser was discovered. A maliciously crafted website could make a phishing attack with address bar spoofing as the address bar was not correct if navigation fails in a loop.

An arbitrary code execution vulnerability was found in the F-Secure Support Tool. A standard user can craft a special configuration file, which when run by administrator can execute any commands.

F-Secure Software Updater 2.20, as distributed in several F-Secure products, downloads installation packages over plain http and does not perform file integrity validation after download. Man-in-the-middle attackers can replace the file with their own executable which will be executed under the SYSTEM account. Note that when Software Updater is configured to install updates automatically, it checks if the downloaded file is digitally signed by default, but does not check the author of the signature. When running in manual mode (default), no signature check is performed.

F-Secure Total Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of F-Secure Total. User interaction on the part of an administrator is required to exploit this vulnerability.

The specific flaw exists within the WithSecure plugin hosting service. By creating a symbolic link, an attacker can abuse the service to create a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-23005.

Certain WithSecure products allow Local privilege escalation via the lhz archive unpack handler. This affects WithSecure Client Security 15, WithSecure Server Security 15, WithSecure Email and Server Security 15, WithSecure Elements Endpoint Protection 17 and later, WithSecure Client Security for Mac 15, WithSecure Elements Endpoint Protection for Mac 17 and later, Linux Security 64 12.0 , Linux Protection 12.0, and WithSecure Atlant (formerly F-Secure Atlant) 1.0.35-1.

An issue was discovered in F-Secure XFENCE and Little Flocker. A maliciously crafted Universal/fat binary can evade third-party code signing checks. By not completing full inspection of the Universal/fat binary, the user of the third-party tool will believe that the code is signed by Apple, but the malicious unsigned code will execute.

Untrusted search path vulnerability in F-Secure Online Scanner allows remote attackers to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse DLL that is located in the same folder as F-SecureOnlineScanner.exe.

In the F-Secure installer in F-Secure SAFE for Windows before 17.6, F-Secure Internet Security before 17.6, F-Secure Anti-Virus before 17.6, F-Secure Client Security Standard and Premium before 14.10, F-Secure PSB Workstation Security before 12.01, and F-Secure Computer Protection Standard and Premium before 19.3, a local user can escalate their privileges through a DLL hijacking attack against the installer. The installer writes the file rm.exe to C:\Windows\Temp and then executes it. The rm.exe process then attempts to load several DLLs from its current directory. Non-admin users are able to write to this folder, so an attacker can create a malicious C:\Windows\Temp\OLEACC.dll file. When an admin runs the installer, rm.exe will execute the attacker's DLL in an elevated security context.

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.

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.
