CVE-2019-13272: Linux Kernel Improper Privilege Management Vulnerability

First published: Tue Jul 16 2019(Updated: )

A flaw in the kernels implementation of ptrace which could inadvertantly grant elevated permissions to an attacker who could abuse the relationship between tracer and the process being traced. The mechanism used to link the process requesting the ptrace and the process being ptraced could allow a local user to obtain root level priviledges by creating an opportunity to abuse the frequently used pattern of dropping privileges and then execve a child with reduced privileges/permissions.
