glibc-2.12-1.149.AXS4.4

Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.

Security issues fixed with this release:

CVE-2014-6040
GNU C Library (aka glibc) before 2.20 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via a multibyte character value of "0xffff" to the iconv function when converting (1) IBM933, (2) IBM935, (3) IBM937, (4) IBM939, or (5) IBM1364 encoded data to UTF-8.

CVE-2014-7817
The wordexp function in GNU C Library (aka glibc) 2.21 does not enforce the WRDE_NOCMD flag, which allows context-dependent attackers to execute arbitrary commands, as demonstrated by input containing "$((`...`))".

Fixed 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. With this update, fixed it.

* An error in the dlopen() library function previously caused recursive calls to dlopen() to terminate unexpectedly or to abort with a library assertion. With this update, fixed it.
