Description

The TCP input data processing function does not validate the length of incoming TCP packets, allowing attackers to read out of bounds and perform memory corruption.

Root cause

An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The TCP input data processing function in pico_tcp.c does not validate the length of incoming TCP packets, which leads to an out-of-bounds read when assembling received packets into a data segment, eventually causing Denial-of-Service or an information leak.

Software

Name
