SUSE SLED11 / SLES11 Security Update : glibc (SUSE-SU-2015:1424-1)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

This update for glibc provides fixes for security and non-security
issues.

These security issues have been fixed :

- CVE-2015-1781: Buffer length after padding in
resolv/nss_dns/dns-host.c. (bsc#927080)

- CVE-2013-2207: pt_chown did not properly check
permissions for tty files, which allowed local users to
change the permission on the files and obtain access to
arbitrary pseudo-terminals by leveraging a FUSE file
system. (bsc#830257)

- CVE-2014-8121: DB_LOOKUP in the Name Service Switch
(NSS) did not properly check if a file is open, which
allowed remote attackers to cause a denial of service
(infinite loop) by performing a look-up while the
database is iterated over the database, which triggers
the file pointer to be reset. (bsc#918187)

- Fix read past end of pattern in fnmatch. (bsc#920338)

These non-security issues have been fixed :

- Fix locking in _IO_flush_all_lockp() to prevent
deadlocks in applications. (bsc#851280)

- Record TTL also for DNS PTR queries. (bsc#928723)

- Fix invalid free in ld.so. (bsc#932059)

- Make PowerPC64 default to non-executable stack.
(bsc#933770)

- Fix floating point exceptions in some circumstances with
exp() and friends. (bsc#933903)

- Fix bad TEXTREL in glibc.i686. (bsc#935286)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
