Scientific Linux Security Update : kernel on SL6.x i386/x86_64 (20190226)

high Nessus Plugin ID 122467

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Security Fix(es) :

- kernel: MIDI driver race condition leads to a double-free (CVE-2018-10902)

Bug Fix(es) :

- Previously backported upstream patch caused a change in the behavior of page fault handler. As a consequence, applications compiled through GNU Compiler Collection (GCC) version 4.4.7 sometimes generated stack access exceeding the 64K limit. Running such applications subsequently triggered a segmentation fault. With this update, the 64k limit check in the page fault handler has been removed. As a result, running the affected applications no longer triggers the segmentation fault in the described scenario.

Note that removing the limit check does not impact the integrity of the kernel itself.

Solution

Update the affected packages.
