-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: glibc security and bug fix update Advisory ID: RHSA-2015:0016-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-0016.html Issue date: 2015-01-07 CVE Names: CVE-2014-6040 CVE-2014-7817 ===================================================================== 1. Summary: Updated glibc packages that fix two security issues and two bugs are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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 Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. An out-of-bounds read flaw was found in the way glibc's iconv() function converted certain encoded data to UTF-8. An attacker able to make an application call the iconv() function with a specially crafted argument could use this flaw to crash that application. (CVE-2014-6040) It was found that the wordexp() function would perform command substitution even when the WRDE_NOCMD flag was specified. An attacker able to provide specially crafted input to an application using the wordexp() function, and not sanitizing the input correctly, could potentially use this flaw to execute arbitrary commands with the credentials of the user running that application. (CVE-2014-7817) The CVE-2014-7817 issue was discovered by Tim Waugh of the Red Hat Developer Experience Team. This update also fixes the following bugs: * Previously, when an address lookup using the getaddrinfo() function for the AF_UNSPEC value was performed on a defective DNS server, the server in some cases responded with a valid response for the A record, but a referral response for the AAAA record, which resulted in a lookup failure. A prior update was implemented for getaddrinfo() to return the valid response, but it contained a typographical error, due to which the lookup could under some circumstances still fail. This error has been corrected and getaddrinfo() now returns a valid response in the described circumstances. (BZ#1172023) * An error in the dlopen() library function previously caused recursive calls to dlopen() to terminate unexpectedly or to abort with a library assertion. This error has been fixed and recursive calls to dlopen() no longer crash or abort. (BZ#1173469) All glibc users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1135841 - CVE-2014-6040 glibc: crash in code page decoding functions (IBM933, IBM935, IBM937, IBM939, IBM1364) 1157689 - CVE-2014-7817 glibc: command execution in wordexp() with WRDE_NOCMD specified 6.
