CVSS 3.0
9.1 criticalCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:HCVE-2018-14938
Critical (9.1). EPSS 2.8% chance of exploitation in the next 30 days.
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).
