| Description: | Summary:
The remote host is missing an update for the 'glibc'
package(s) announced via the referenced advisory.
Vulnerability Insight:
The glibc packages provide the standard C
libraries (libc), POSIX thread libraries (libpthread), standard math libraries
(libm), and the name service cache daemon (nscd) used by multiple programs on
the system. Without these libraries, the Linux system cannot function correctly.
Security Fix(es):
* A stack overflow vulnerability was found in nan* functions that could
cause applications, which process long strings with the nan function, to
crash or, potentially, execute arbitrary code. (CVE-2014-9761)
* It was found that out-of-range time values passed to the strftime()
function could result in an out-of-bounds memory access. This could lead to
application crash or, potentially, information disclosure. (CVE-2015-8776)
* An integer overflow vulnerability was found in hcreate() and hcreate_r()
functions which could result in an out-of-bounds memory access. This could
lead to application crash or, potentially, arbitrary code execution.
(CVE-2015-8778)
* A stack based buffer overflow vulnerability was found in the catopen()
function. An excessively long string passed to the function could cause it
to crash or, potentially, execute arbitrary code. (CVE-2015-8779)
