| 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) * It was found that the
dynamic loader did not sanitize the LD_POINTER_GUARD environment variable. An
attacker could use this flaw to bypass the pointer guarding protection on
set-user-ID or set-group-ID programs to execute arbitrary code with the
permissions of the user running the application. (CVE-2015-8777) Additional
Changes: For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.4 Release Notes linked from the References section.
