RHEL 6 : glibc (RHSA-2016:1207)
Medium Nessus Plugin ID 91497
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionAn update for glibc is now available for Red Hat Enterprise Linux 6.5 Advanced Update Support.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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) :
* It was discovered that, under certain circumstances, glibc's getaddrinfo() function would send DNS queries to random file descriptors. An attacker could potentially use this flaw to send DNS queries to unintended recipients, resulting in information disclosure or data loss due to the application encountering corrupted data.
SolutionUpdate the affected packages.
