New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

An issue was discovered in wifipcap/wifipcap.cpp in TCPFLOW through 1.5.0-alpha. There is an integer overflow in the function handle_prism during caplen processing. If the caplen is less than 144, one can cause an integer overflow in the function handle_80211, which will result in an out-of-bounds read and may allow access to sensitive memory (or a denial of service).
