We recommend that you upgrade your glibc packages.");
    script_tag(name: "summary",   value: "Several vulnerabilities have been fixed
in the GNU C Library, glibc.

The first vulnerability listed below is considered to have critical
impact.

CVE-2015-7547 
The Google Security Team and Red Hat discovered that the glibc
host name resolver function, getaddrinfo, when processing
AF_UNSPEC queries (for dual A/AAAA lookups), could mismanage its
internal buffers, leading to a stack-based buffer overflow and
arbitrary code execution. This vulnerability affects most
applications which perform host name resolution using getaddrinfo,
including system services.

CVE-2015-8776 
Adam Nielsen discovered that if an invalid separated time value
is passed to strftime, the strftime function could crash or leak
information. Applications normally pass only valid time
information to strftime; no affected applications are known.

CVE-2015-8778 
Szabolcs Nagy reported that the rarely-used hcreate and hcreate_r
functions did not check the size argument properly, leading to a
crash (denial of service) for certain arguments. No impacted
applications are known at this time.

CVE-2015-8779 
The catopen function contains several unbound stack allocations
(stack overflows), causing it the crash the process (denial of
service). No applications where this issue has a security impact
are currently known.

While it is only necessary to ensure that all processes are not using
the old glibc anymore, it is recommended to reboot the machines after
applying the security upgrade.");

software version using the apt package manager.");
