Description:

This document describes how to perform an update of the Linux glibc library on Linux-based LSM and LSR systems.

Due to the vulnerability widely reported in the media, we strongly recommend that you update the Linux glibc library soon.


Procedures:

1) Updating the glibc library on the LSM system:

1.1) Type the following command into the command line of the Linux system. The system indicates that an update to the glibc library is available in the "updates" repository.

    $ yum info glibc


1.2) Enter the following command to start the update:
    $ yum -y update glibc





2) Updating the glibc library on the LSR system:

2.1) Type the following command into the command line of the Linux system. This triggers an automatic update.

2.2) Finally, check that the updated glibc library is actually on your system by entering the following command:
    apt-cache show libc6

The output that follows must include the version information marked in green:
    Package: libc6

    Description: GNU C Library: Shared libraries
    Contains the standard libraries that are used by nearly all programs on
    the system. This package includes shared versions of the standard C library
    and the standard math library, as well as many others.
