Details

It was discovered that Sudo incorrectly handled memory when parsing command
lines. A local attacker could possibly use this issue to obtain unintended
access to the administrator account. (CVE-2021-3156)

It was discovered that the Sudo sudoedit utility incorrectly handled
checking directory permissions. A local attacker could possibly use this
issue to bypass file permissions and determine if a directory exists or
not. (CVE-2021-23239)
