CVE-2024-24478Network attack vector

Disputed denial of service via BGP option length

Published Feb 21, 2024 · Updated Aug 1, 2024

The disputed denial-of-service claim in Wireshark before 4.2.0 alleges that remote attackers can crash analysis with crafted BGP OPEN data. The cited change widens dissect_bgp_open's optlen from 8 to 16 bits so an RFC 9072 extended length cannot wrap and advance the parsing offset incorrectly. Wireshark states that the CVE rests on invalid assumptions and that no release was affected.
