  "summary": "Updated sudo packages fix security vulnerability",
  "details": "A vulnerability in functionality for adding support of SHA-2 digests along\nwith the command was found. The sudoers plugin performs this digest\nverification while matching rules, and later independently calls execve()\nto execute the binary. This results in a race condition if the digest\nfunctionality is used as suggested (in fact, the rules are matched before\nthe user is prompted for a password, so there is not negligible time frame\nto replace the binary from underneath sudo) (CVE-2015-8239).\n",
