1) Insufficient verification of data authenticity (CVE-ID: CVE-2007-3848)

The vulnerability allows a local user to perform service disruption.

Linux kernel 2.4.35 and other versions allows local users to send arbitrary signals to a child process that is running at higher privileges by causing a setuid-root parent process to die, which delivers an attacker-controlled parent process death signal (PR_SET_PDEATHSIG).
