HTTP3 dissector crash in Wireshark 4.6.0 and 4.6.1 allows denial of service
The product manages a group of objects or resources and performs a separate memory allocation for each object, but it does not properly limit the total amount of memory that is consumed by all of the combined objects.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Wireshark | Wireshark | 4.6.0 (including) | 4.6.2 (excluding) |
While the product might limit the amount of memory that is allocated in a single operation for a single object (such as a malloc of an array), if an attacker can cause multiple objects to be allocated in separate operations, then this might cause higher total memory consumption than the developer intended, leading to a denial of service.
