(Red Hat Issues Fix) Glibc Stack/Heap Memory Allocation Error Lets Local Users Gain Elevated Privileges
SecurityTracker Alert ID:  1038717
SecurityTracker URL:  http://securitytracker.com/id/1038717
CVE Reference:   CVE-2017-1000366   (Links to External Site)
Date:  Jun 20 2017
Impact:   Execution of arbitrary code via local system, Root access via local system, User access via local system
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 2.25 and prior
Description:   A vulnerability was reported in Glibc. A local user can obtain elevated privileges on the target system.

A local user can supply specially crafted LD_LIBRARY_PATH values to trigger a stack memory allocation flaw in certain cases and execute arbitrary code on the target system with elevated privileges.

The stack guard-page memory gap can be "jumped" in cases where heap memory and stack memory are adjacent.

The original advisory is available at:

https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt

Qualys Research Labs reported this vulnerability.

Impact:   A local user can obtain elevated privileges on the target system.
Solution:   Red Hat has issued a fix.

3. Description:

The glibc packages provide the standard C libraries (libc), POSIX thread
libraries (libpthread), standard math libraries (libm), and the name
service cache daemon (nscd) used by multiple programs on the system.
Without these libraries, the Linux system cannot function correctly.

Security Fix(es):

* A flaw was found in the way memory was being allocated on the stack for
user space binaries. If heap (or different memory region) and stack memory
regions were adjacent to each other, an attacker could use this flaw to
jump over the stack guard gap, cause controlled memory corruption on
process stack or the adjacent memory region, and thus increase their
privileges on the system. This is glibc-side mitigation which blocks
processing of LD_LIBRARY_PATH for programs running in secure-execution mode
and reduces the number of allocations performed by the processing of
LD_AUDIT, LD_PRELOAD, and LD_HWCAP_MASK, making successful exploitation of
this issue more difficult. (CVE-2017-1000366)

Red Hat would like to thank Qualys Research Labs for reporting this issue.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all services linked to the glibc library
must be restarted, or the system rebooted.

5. Bugs fixed (https://bugzilla.redhat.com/):

1452543 - CVE-2017-1000366 glibc: heap/stack gap jumping via unbounded stack allocations
