CVE-2018-14938

Priority
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).
Ubuntu-Description
It was discovered that tcpflow mishandled certain crafted input, resulting in
an integer overflow. An attacker could use this vulnerability to leak
sensitive information or cause a denial of service (crash).
