Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/sudo-1.9.15-i586-1_slack15.0.txz: Upgraded.
 The sudoers plugin has been modified to make it more resilient to ROWHAMMER
 attacks on authentication and policy matching.
 The sudoers plugin now constructs the user time stamp file path name using
 the user-ID instead of the user name. This avoids a potential problem with
 user names that contain a path separator ('/') being interpreted as part of
 the path name.
 For more information, see:

 (* Security fix *)
+--------------------------+");
