" A race condition was found in the way the Linux kernel's memory subsystem. Further digging into this, revealed that Python has a list of search paths for its libraries; meaning there is an opportunity for privilege escalation depending on mis. The exploit proceeds in a similar fashion to the previous two except that once it’s got the thread port it can directly point RIP to the gadget address rather than overwriting a function pointer. Red Hat, assigned the flaw as "important" with a CVSS score of 7. Finding an exploit that allows me to execute code allows me instant root access. Assume we are accessing the target system as a non-root user and we found suid bit enabled binaries, then those file/program/command can run with root privileges. sudo allows a permitted user to execute a command as the superuser or another user, as specified in the sudoers file. This is an unusually high number, which increases the chances that one or more will be vulnerable to privilege escalation. Vulnerability analysis.
