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).

Affected: Ubuntu:16.04:LTS: tcpflow, Ubuntu:18.04:LTS: tcpflow

It was discovered that tcpflow incorrectly handled certain malformed network packets. A remote attacker could send these packets to a target system, causing tcpflow to crash or possibly disclose sensitive information.
