CVE-2012-4068: Heap-based buffer overflow in the SoapServer service in Citrix Provisioning Services 5.0, 5.1, 5.6, 5.6 SP1...

Security readout for executives and security teams

This is a remote code execution flaw in Citrix Provisioning Services SoapServer. An attacker who can reach the vulnerable service may be able to crash it or run code on the server. The supplied sources do not include CVSS, patch details, or evidence of active exploitation. Exposure is likely limited to environments still running the named legacy Citrix Provisioning Services versions, especially where SoapServer is reachable from untrusted networks or broad internal segments. Treat as high priority for any remaining legacy Citrix Provisioning deployment because the stated impact is remote code execution. Urgency drops if the product is absent, fully retired, patched, or isolated from untrusted access. Mitigation focus: Check Citrix CTX133039 for the vendor-supported fix or workaround.; Upgrade or remove affected Citrix Provisioning Services versions where possible.; Restrict SoapServer access to trusted administrative networks only..
