package/sudo: security bump to version 1.9.5p1
- Fixes CVE-2021-23239, a potential information leak in sudoedit that
could be used to test for the existence of directories not normally
accessible to the user in certain circumstances. When creating a new
file, sudoedit checks to make sure the parent directory of the new
file exists before running the editor. However, a race condition
exists if the invoking user can replace (or create) the parent
directory. If a symbolic link is created in place of the parent
directory, sudoedit will run the editor as long as the target of the
link exists. If the target of the link does not exist, an error
message will be displayed. The race condition can be used to test for
the existence of an arbitrary directory. However, it cannot be used to
write to an arbitrary location.
- Fixes CVE-2021-23240, a flaw in the temporary file handling of
sudoedit's SELinux RBAC support. On systems where SELinux is enabled,
a user with sudoedit permissions may be able to set the owner of an
arbitrary file to the user-ID of the target user. On Linux kernels
that support protected symlinks setting
/proc/sys/fs/protected_symlinks to 1 will prevent the bug from being
exploited. For more information, see Symbolic link attack in
SELinux-enabled sudoedit.
