Summary

wireshark security update

Details

Wireshark allows you to examine protocol data stored in files or as it is captured from wired or wireless (WiFi or Bluetooth) networks, USB devices, and many other sources. It supports dozens of protocol capture file formats and understands more than a thousand protocols.

Security Fix(es):

Excessive memory consumption in MS-WSP dissector in Wireshark 3.4.0 to 3.4.4 and 3.2.0 to 3.2.12 allows denial of service via packet injection or crafted capture file(CVE-2021-22207)

Improper URL handling in Wireshark 3.4.0 to 3.4.3 and 3.2.0 to 3.2.11 could allow remote code execution via via packet injection or crafted capture file.(CVE-2021-22191)

Crash in the Sysdig Event dissector in Wireshark 3.6.0 and 3.4.0 to 3.4.10 allows denial of service via packet injection or crafted capture file(CVE-2021-4181)

Infinite loop in the RTMPT dissector in Wireshark 3.6.0 and 3.4.0 to 3.4.10 allows denial of service via packet injection or crafted capture file(CVE-2021-4185)

Severity

8.8 (High)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
