AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A denial-of-service vulnerability in F-Secure Atlant and certain WithSecure products allows crash of the scanning engine when processing a fuzzed APK file.
Vulnerability
A denial-of-service vulnerability exists in the scanning engine of F-Secure Atlant and certain WithSecure products. When scanning a specially crafted (fuzzed) APK file, the engine can crash, leading to a denial of service. The affected versions are not explicitly disclosed in the available references [1][2].
Exploitation
An attacker needs to deliver a malicious APK file to the target system. No authentication is required if the file is scanned automatically (e.g., on-access scanning). The attacker crafts a fuzzed APK that triggers the crash during scanning.
Impact
Successful exploitation causes the scanning engine to crash, resulting in a denial of service. The system may become unprotected until the engine is restarted. No code execution or data compromise is indicated.
Mitigation
F-Secure and WithSecure have likely released updates; however, the specific fixed version is not provided in the available references [1][2]. Users should consult the vendor's advisory pages for the latest patches.
