Security Bulletin

Summary

A GNU C library (glibc) stack-based buffer overflow in getaddrinfo() 
vulnerability affects IBM Security Privileged Identity Manager Virtual 
Appliance

Vulnerability Details

CVEID: CVE-2015-7547

DESCRIPTION: GNU C Library (glibc) is vulnerable to a stack-based buffer 
overflow, caused by improper bounds checking by the nss_dns backend for the 
getaddrinfo() function when performing dual A/AAAA DNS queries. By sending a 
specially crafted DNS response, a remote attacker could overflow a buffer and
execute arbitrary code on the system or cause the application to crash.

CVSS Base Score: 8.1

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/110662 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

Affected Products and Versions

IBM Security Identity Manager versions 2.0,0, 2.0.1, 2.0.2

Remediation/Fixes

Product 					VRMF 	Remediation/First Fix

IBM Security Privileged Identity Manager 
 Virtual Appliance 				2.0.2 	apply 2.0.2-ISS-ISPIM-VA-GLIBC.fixpack

IBM Security Privileged Identity Manager 	2.0.0	Upgrade firmware to ISPIM 2.0.2
 Virtual Appliance 				2.0.1 	and apply 2.0.2-ISS-ISPIM-VA-GLIBC.fixpack

Once updates have been applied, any process using glibc will need to be 
restarted. Given that nearly all system processes use glibc, rebooting after 
upgrading is suggested.

IBM recommends that you review your entire environment to identify vulnerable
releases of glibc including your Operating Systems and take appropriate 
mitigation and remediation actions. Please contact your Operating System 
provider for more information.
