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.
