CVE-2024-8250Public exploit

Analyzer crash via stack-key lifetime error

Published Aug 28, 2024 · Updated Mar 27, 2026

Expired pointer dereference in Wireshark 4.0.0 through 4.0.16 and 4.2.0 through 4.2.6 allows attackers to crash the analyzer. The NTLMSSP dissector stores a stack-created decryption key in a hash table; a later header_equal comparison dereferences the expired key and reads beyond the stack object. Triggering requires injecting a malformed packet into a live capture or inducing a user to open a crafted capture file, and the documented consequence is process termination.
