Detail

Problem Description:

An update for glibc is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64

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 stack overflow vulnerability was found in nan* functions that could cause applications, which process long strings with the nan function, to crash or, potentially, execute arbitrary code. (CVE-2014-9761)

* It was found that out-of-range time values passed to the strftime() function could result in an out-of-bounds memory access. This could lead to application crash or, potentially, information disclosure. (CVE-2015-8776)

* An integer overflow vulnerability was found in hcreate() and hcreate_r() functions which could result in an out-of-bounds memory access. This could lead to application crash or, potentially, arbitrary code execution. (CVE-2015-8778)

* A stack based buffer overflow vulnerability was found in the catopen() function. An excessively long string passed to the function could cause it to crash or, potentially, execute arbitrary code. (CVE-2015-8779)

Additional Changes:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 6.9 Release Notes and Red Hat Enterprise Linux 6.9 Technical Notes linked from the References section.

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/):

1012343 - Thread issue in glibc can cause the application to not get any identity information 1101858 - glibc: Add el_GR@euro, ur_IN, and wal_ET locales 1223095 - access to uninitialized memory in getaddrinfo if nscd is running 1270950 - getaddrinfo() takes long time when lots of IP addresses are configured 1300299 - CVE-2015-8776 glibc: Segmentation fault caused by passing out-of-range data to strftime() 1300303 - CVE-2015-8778 glibc: Integer overflow in hcreate and hcreate_r 1300310 - CVE-2014-9761 glibc: Unbounded stack allocation in nan* functions 1300312 - CVE-2015-8779 glibc: Unbounded stack allocation in catopen function 1338673 - glibc: GCC 6 enablement for struct sockaddr_storage [el6] 1373646 - tzdata-update uses default umask 1416496 - getaddrinfo() call returns wrong IPv6 address if nscd is used
