- Update to glibc 2.24
* The minimum Linux kernel version that this version of the GNU C Library
can be used with is 3.2
* The pap_AN locale has been deleted
* The readdir_r and readdir64_r functions have been deprecated
* The type `union wait' has been removed
* A new NSS action is added to facilitate large distributed system
administration
* The deprecated __malloc_initialize_hook variable has been removed from
the API
* The long unused localedef --old-style option has been removed
* nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf are added
to libm
* An unnecessary stack copy in _nss_dns_getnetbyname_r was removed
(CVE-2016-3075)
* Previously, getaddrinfo copied large amounts of address data to the
stack, even after the fix for CVE-2013-4458 has been applied,
potentially resulting in a stack overflow. getaddrinfo now uses a
heap allocation instead (CVE-2016-3706)
* The glob function suffered from a stack-based buffer overflow when it
was called with the GLOB_ALTDIRFUNC flag and encountered a long file
name (CVE-2016-1234)
* The Sun RPC UDP client could exhaust all available stack space when
flooded with crafted ICMP and UDP messages (CVE-2016-4429)
* The IPv6 name server management code in libresolv could result in a
memory leak for each thread which is created, performs a failing
naming lookup, and exits (CVE-2016-5417)
