9.1 (Critical) CVSS_V3 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H CVSS Calculator

Summary

[none]

Details

An issue was discovered in wifipcap/wifipcap.cpp in TCPFLOW through 1.5.0-alpha. There is an integer overflow in the function handleprism during caplen processing. If the caplen is less than 144, one can cause an integer overflow in the function handle80211, which will result in an out-of-bounds read and may allow access to sensitive memory (or a denial of service).
