CentOS Update for glibc CESA-2015:0092 centos6

Published: 2015-01-28 05:10:55
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Summary:
Check the version of glibc

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The glibc Linux Distribution Packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. A heap-based buffer overflow was found in glibc's __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. (CVE-2015-0235) Red Hat would like to thank Qualys for reporting this issue. All glibc users are advised to upgrade to these updated Linux Distribution Packages, which contain a backported patch to correct this issue.

Affected Versions:
glibc on CentOS 6

Recommendations:
Please install the updated Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
