Package        : linux
Version        : 3.2.89-2
Debian Bug     : 865303

The security update announced as DLA-993-1 caused regressions for some
applications using Java - including jsvc, LibreOffice and Scilab - due
to the fix for CVE-2017-1000364. Updated packages are now available to
correct this issue. For reference, the relevant part of the original
advisory text follows.


    The Qualys Research Labs discovered that the size of the stack guard
    page is not sufficiently large. The stack-pointer can jump over the
    guard-page and moving from the stack into another memory region
    without accessing the guard-page. In this case no page-fault
    exception is raised and the stack extends into the other memory
    region. An attacker can exploit this flaw for privilege escalation.

    The default stack gap protection is set to 256 pages and can be
    configured via the stack_guard_gap kernel parameter on the kernel
    command line.
