Test ID:1.3.6.1.4.1.25623.1.0.871831
Category:Red Hat Local Security Checks
Title:RedHat Update for glibc RHSA-2017:1480-01
Summary:The remote host is missing an update for the 'glibc'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'glibc'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
glibc on
Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
