Security Bulletin
Summary
A GNU C library (glibc) stack-based buffer overflow in getaddrinfo()
vulnerability affects IBM Security Access Manager for Web.
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 Access Manager for Web 7.0 (appliances)
IBM Security Access Manager for Web 8.0, all firmware versions
IBM Security Access Manager for Web 9.0, all firmware versions
Remediation/Fixes
The table below provides links to patches for all affected versions. Follow
the installation instructions in the README file included with the patch.
Product VRMF APAR Remediation
IBM Security Access Manager for Web 7.0 (appliance) IV81894 1. Apply Interim Fix 22:
7.0.0-ISS-WGA-IF0022
IBM Security Access Manager for Web 8.0.0.0 - 1. For 8.0-8.0.1.2 environments, upgrade to 8.0.1.3:
8.0.1.3 IV81882 8.0.1-ISS-WGA-FP0003
2. Apply 8.0.1.3 Interim Fix 5:8.0.1.3-ISS-WGA-IF0005
IBM Security Access Manager 9.0 IV81837 1. For 9.0 environments, upgrade to
9.0.0.1:
9.0.0-ISS-ISAM-FP0001
2. Apply 9.0.0.1 Interim Fix 2:
9.0.0.1-ISS-ISAM-IF0002
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.
Workarounds and Mitigations
None.
