  - CVE-2010-0542: The _WriteProlog function in texttops.c in texttops in the Text Filter subsystem
  does not check the return values of certain calloc calls.

  - CVE-2010-2431: The cupsFileOpen function allows local users, with lp group membership, to
  overwrite arbitrary files via a symlink attack.

  - CVE-2010-2432: The cupsDoAuthentication function in auth.c in the client, when HAVE_GSSAPI is
  omitted, does not properly handle a demand for authorization, which allows remote CUPS servers to
  cause a denial of service (infinite loop) via HTTP_UNAUTHORIZED responses.");
