CVE-2024-27359Network attack vector

Scanner hang via nonterminating archive processing

Published Feb 25, 2024 · Updated Aug 5, 2024

Infinite-loop DoS in affected WithSecure products allows remote attackers to hang the scanner by submitting a crafted archive file. The shared engine scanner fails to terminate while processing the archive, consuming execution indefinitely instead of rejecting or completing the file. Any remote path that submits files for scanning can trigger the hang in the listed version families; the reported effect is service interruption without data exposure or modification.
