Lifecycle Timeline
1DescriptionNVD
Multiple 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.
AnalysisAI
Multiple 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. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. Multiple 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. Affected products include: F-Secure Atlant, F-Secure Elements Endpoint Protection, F-Secure Linux Security, Withsecure Cloud Protection For Salesforce, Withsecure Elements Collaboration Protection.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
