CVE-2013-2561: OpenFabrics ibutils 1.5.7 allows local users to overwrite arbitrary files via a symlink attack on (1) ibdia...

Security readout for executives and security teams

This is an old local file-overwrite flaw in OpenFabrics ibutils 1.5.7. A local user on a shared system could abuse predictable temporary files in /tmp to cause ibutils output to overwrite another file. Business urgency is highest on multi-user Linux or HPC systems where ibutils is installed and run with elevated privileges. Likely exposure is limited to systems with OpenFabrics ibutils 1.5.7 or affected downstream packages installed, especially shared InfiniBand/HPC environments with local user access. Internet-facing exposure is not indicated by the sources. Treat as a targeted maintenance item, not an internet emergency. Prioritize shared HPC or Linux infrastructure where local users can log in and where ibutils may run with elevated privileges. Mitigation focus: Apply vendor updates or advisories that address CVE-2013-2561 where available.; Check Red Hat RHSA-2013:1661 and Oracle guidance for downstream package status.; Remove ibutils from systems where InfiniBand diagnostics are not required..
