"The remote host is affected by the vulnerability described in GLSA-200704-22
(BEAST: Denial of Service)

    BEAST, which is installed as setuid root, fails to properly check
    whether it can drop privileges accordingly if seteuid() fails due to a
    user exceeding assigned resource limits.
  
Impact :

    A local user could exceed his resource limit in order to prevent the
    seteuid() call from succeeding. This may lead BEAST to keep running
    with root privileges. Then, the local user could use the 'save as'
    dialog box to overwrite any file on the vulnerable system, potentially
    leading to a Denial of Service.
  
Workaround :

    There is no known workaround at this time."

    Several X.org libraries and X.org itself contain system calls to

Impact :

    Local users could deliberately exceed their assigned resource limits
    and elevate their privileges after an unsuccessful set*uid() system
    call. This requires resource limits to be enabled on the machine.
