Dissection engine LZ77 decompression crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
A flaw was found in Wireshark. A remote attacker could exploit a dissection engine LZ77 decompression crash by crafting a malicious packet. This vulnerability leads to a Denial of Service (DoS) condition, making the application unavailable.
Меры по смягчению последствий
To mitigate this issue, users should avoid opening untrusted or suspicious packet capture files with Wireshark. Running Wireshark in a sandboxed environment can further limit the potential impact of processing malicious data.
