Security Bulletin: Open Source GNU glibc Vulnerabilities which is used by IBM
OS Images for RedHat Linux in IBM PureApplication Systems (CVE-2017-1000366)
More support for:
18.104.22.168, 22.214.171.124, 126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11

There are vulnerabilities in the Open Source GNU glibc that is used by the OS
Images for IBM PureApplication Software Suite, IBM Bluemix Local System and
IBM PureApplication System/Software
Glibc could allow a local attacker to execute arbitrary code on the system,
caused by a vulnerability that allows specially crafted LD_LIBRARY_PATH
values to manipulate the heap/stack. By using specially-crafted crafted
LD_LIBRARY_PATH values, an attacker could exploit this vulnerability to
trigger a stack memory allocation flaw and execute arbitrary code on the
CVSS Base Score: 7.4

Affected Products and Versions
IBM OS Image for Red Hat Linux Systems 18.104.22.168
IBM OS Image for Red Hat Linux Systems 22.214.171.124
IBM OS Image for Red Hat Linux Systems 126.96.36.199
IBM OS Image for Red Hat Linux Systems 188.8.131.52
IBM OS Image for Red Hat Linux Systems 184.108.40.206
IBM OS Image for Red Hat Linux Systems 220.127.116.11
IBM OS Image for Red Hat Linux Systems 18.104.22.168
The deployed Red Hat Linux-based virtual machines on IBM PureApplication
System types are affected. The solution is to apply the following emergency
fix to the deployed virtual machines.
1. Import the fix into the Emergency Fix catalogue.
2. For deployed instances, apply this emergency fix on the VM. The glibc
library on the IBM OS Image for Red Hat Linux Systems will be updated to
contain the fix.
3. Restart the deployed instance after the fix is applied.
4. Verify that this fix does not cause any compatibility issues.
Optionally, the operating system vendor provides a glibc fix. The fix can be
applied by running the command yum update glibc within the deployed virtual
machine to upgrade to the latest glibc version.
