CVE-2022-28879
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 · uneditedA Denial-of-Service (DoS) vulnerability was discovered in F-Secure Atlant and in certain WithSecure products whereby the scanning the aepack.dll component can crash the scanning engine.
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 confidenceA DoS vulnerability exists in F-Secure Atlant and certain WithSecure products where scanning a specific file (aepack.dll) causes the antivirus scanning engine to crash, rendering the protection unavailable until restart.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 or WithSecure productsReview installed software list or check for F-Secure/WithSecure service processes (such as fssp, fsma, fseplr, or withsecured)Affected if Any of the following products are present: F-Secure Elements Endpoint Protection, F-Secure Atlant, F-Secure Cloud Protection for Salesforce, F-Secure Elements Collaboration Protection, F-Secure Internet Gatekeeper, F-Secure Linux Security, or F-Secure Linux Security 64
-
Confirm scanning engine is enabledCheck if the real-time scanning service or on-demand scanner daemon is running. On Linux, check for processes like 'fssp' or 'fseplr' and verify their status is active/running.Affected if The scanning engine is actively running and available for file scanning operations
-
Locate aepack.dll on the systemSearch for a file named aepack.dll in common locations such as system directories, application data folders, or recent downloadsAffected if The aepack.dll file exists on the system and is accessible to the antivirus scanner
If a vulnerable F-Secure/WithSecure product is installed with the scanning engine enabled, and the aepack.dll file is present, scanning that file will crash the protection engine until service restart.

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 dataUpdate to patched versions of F-Secure/WithSecure products that properly handle the aepack.dll file without crashing the scanning engine.
