fixed :

  - CVE-2017-2619: symlink race permits opening files
    outside share directory (bsc#1027147). For SUSE Linux
    Enterprise 11 SP4 this is a re-issue of the update, a
    regression in the fix has been addressed (bsc#1036283,
    bso#12721).

Note that Tenable Network Security has extracted the preceding

has attempted to automatically clean and format it as much as possible
without introducing additional issues."
