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):
Multiple protocol dissector infinite loops in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allow denial of service.(CVE-2026-15163)
Crash in ciscodump 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows denial of service due to a heap-based buffer overflow.(CVE-2026-15164)
IEEE 802.11 protocol dissector crash in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows denial of service due to a stack-based buffer overflow.(CVE-2026-15166)
DBS Etherwatch file parser crash in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows denial of service due to a stack-based buffer overflow.(CVE-2026-15167)
BLF file parser in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows possible information disclosure(CVE-2026-15168)
UMTS FP protocol dissector crash in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows denial of service via a heap-based buffer overflow.(CVE-2026-15169)
Z39.50 protocol dissector crash in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows denial of service due to a heap-based buffer overflow.(CVE-2026-15170)
A NULL pointer dereference vulnerability in the SSH protocol dissector of Wireshark versions 4.6.0 through 4.6.6 and 4.4.0 through 4.4.16 allows remote attackers to cause a denial of service via crafted traffic.(CVE-2026-15171)
FMP/NOTIFY protocol dissector crash in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows denial of service due to unchecked input for loop condition.(CVE-2026-15172)
A heap-based buffer overflow vulnerability in the Catapult DCT2000 protocol dissector in Wireshark 4.6.0 through 4.6.6 and 4.4.0 through 4.4.16 allows denial of service via a crafted packet or traffic capture file, causing the dissector to crash.(CVE-2026-15174)
Severity
7.5 (High)

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.
