Descriptions
popd in bash might allow local users to bypass the restricted shell and cause a use-after-free via a crafted address.
popd en bash podrían permitir a usuarios locales eludir el shell restringido y provocar un uso después de liberación de memoria a través de una dirección manipulada.
A denial of service flaw was found in the way bash handled popd commands. A poorly written shell script could cause bash to crash resulting in a local denial of service limited to a specific bash session.
