    An update that solves 6 vulnerabilities and has three fixes 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
