Additional mitigation guidance and recommended practices are publicly available in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not remotely exploitable.
Stack-based buffer overflow vulnerabilities caused by processing specially crafted .dpb files may allow an attacker to remotely execute arbitrary code.
Specially crafted .dpb files could exploit a use-after-free vulnerability.
Specially crafted .dpb files may cause the system to write outside the intended buffer area.
An access of resource using incompatible type (‘type confusion’) vulnerability may allow an attacker to execute remote code when processing specially crafted .dpb files.
Steven Seeley of Source Incite reported these vulnerabilities to ICS-CERT.
