Summary

A local privilege escalation vulnerability exists in Bash that enables local users to bypass the restricted shell. This is accomplished through a manipulated 'popd' command, which can lead to a use-after-free situation via a specially crafted address. As a result, unauthorized actions may be performed, posing potential risks to system integrity. Users should apply necessary patches to mitigate these security concerns.
