Thierry Carrez (email@example.com) of the OpenStack Project reports:
Title: Keystone denial of service through invalid token requests
Reporter: Dan Prince (Red Hat)
Affects: All versions
Dan Prince of Red Hat reported a vulnerability in token creation error
handling in Keystone. By requesting lots of invalid tokens, an
unauthenticated user may fill up logs on Keystone API servers disks,
potentially resulting in a denial of service attack against Keystone.
See attached patches for current development tree (Grizzly) and the
Folsom and Essex series. Unless a flaw is discovered in them, these
proposed patches will be merged to Keystone master, stable/folsom and
stable/essex branches on the public disclosure date.
