DescriptionCVE.org

IEEE 802.11 protocol dissector crash in Wireshark 4.6.0 to 4.6.2 and 4.4.0 to 4.4.12 allows denial of service

AnalysisAI

Wireshark versions 4.4.0-4.4.12 and 4.6.0-4.6.2 crash when processing malformed IEEE 802.11 wireless packets, enabling a remote denial of service attack that requires user interaction to view the malicious traffic. An attacker can exploit this out-of-bounds write vulnerability by crafting a specially formatted packet, causing the application to become unavailable without requiring authentication. No patch is currently available for this issue.

Technical ContextAI

Classified as CWE-787 (Out-of-bounds Write). Affects Wireshark. IEEE 802.11 protocol dissector crash in Wireshark 4.6.0 to 4.6.2 and 4.4.0 to 4.4.12 allows denial of service

RemediationAI

Monitor vendor advisories for a patch. Enable ASLR, DEP/NX, and stack canaries where possible. Restrict network access to the affected service where possible.
