is now available.

Description:

This update for glibc fixes the following security issues:

– CVE-2015-7547: A stack-based buffer overflow in getaddrinfo allowed
remote attackers to cause a crash or execute arbitrary code via crafted
and timed DNS responses (bsc#961721)
– CVE-2015-8777: Insufficient checking of LD_POINTER_GUARD environment
variable allowed local attackers to bypass the pointer guarding
protection of the dynamic loader on set-user-ID and set-group-ID
programs (bsc#950944)
– CVE-2015-8776: Out-of-range time values passed to the strftime function
may cause it to crash, leading to a denial of service, or potentially
disclosure information (bsc#962736)
– CVE-2015-8778: Integer overflow in hcreate and hcreate_r could have
caused an out-of-bound memory access. leading to application crashes or,
potentially, arbitrary code execution (bsc#962737)
– CVE-2014-9761: A stack overflow (unbounded alloca) could have caused
applications which process long strings with the nan function to crash
or, potentially, execute arbitrary code. (bsc#962738)
– CVE-2015-8779: A stack overflow (unbounded alloca) in the catopen
function could have caused applications which pass long strings to the
catopen function to crash or, potentially execute arbitrary code.
(bsc#962739)

The following non-security bugs were fixed:

– bsc#955647: Resource leak in resolver
– bsc#956716: Don’t do lock elision on an error checking mutex
– bsc#958315: Reinitialize dl_load_write_lock on fork
