CVE-2022-28874
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMultiple Denial-of-Service vulnerabilities was discovered in the F-Secure Atlant and in certain WithSecure products while scanning fuzzed PE32-bit files cause memory corruption and heap buffer overflow which eventually can crash the scanning engine. The exploit can be triggered remotely by an attacker.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceF-Secure Atlant and certain WithSecure products contain multiple DoS vulnerabilities in their scanning engine. When scanning specially crafted fuzzed PE32-bit files, memory corruption and heap buffer overflow occur, causing the scanning engine to crash. The vulnerability can be triggered remotely by an attacker who can deliver a malicious file for scanning.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed F-Secure/WithSecure productsRun 'rpm -qa | grep -iE "(f-secure|withsecure|atlant|elements)"' on Linux or check Programs and Features on Windows to list installed security productsAffected if Any of the following products appear: F-Secure Atlant, F-Secure Elements Endpoint Protection, F-Secure Linux Security, WithSecure Cloud Protection For Salesforce, or WithSecure Elements Collaboration Protection
-
Verify scanning engine module is activeCheck if the real-time or on-demand scanning service is running. On Linux, run 'ps aux | grep -iE "(f-secure|withsecure)"' or check systemctl status for f-secure or withsecure services. On Windows, check if the antivirus service is running in Services.Affected if The scanning engine service is running or scheduled scans are enabled
-
Confirm PE32 scanning is enabledReview the product configuration for scanning settings. Check if scanning of executable files (PE32) is enabled in the antivirus policy or configuration file. Look for settings like 'scan executables', 'scan pe files', or real-time scanning toggle.Affected if PE32 file scanning is enabled (which is the default configuration)
If any of the affected F-Secure or WithSecure products are installed with the scanning engine enabled, the environment is vulnerable since all versions are affected by this flaw.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patches from F-Secure/WithSecure. Organizations should ensure their security product installations are updated to the latest versions that address this vulnerability.
