Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Unspecified vulnerability in Oracle Solaris 8, 9, and 10 allows remote attackers to affect confidentiality, integrity, and availability, related to CDE Calendar Manager Service Daemon and RPC. NOTE: the previous information was obtained from the January 2011 CPU. Oracle has not commented on claims from other software vendors that this affects other operating systems, such as HP-UX, or claims from a reliable third party that this is a buffer overflow in rpc.cmsd via long XDR-encoded ASCII strings in RPC call 10.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix Moderate confidence

Apply January 2011 CPU patches for Oracle Solaris 10 (and Solaris 8/9 if still in support)

  1. Apply Oracle Critical Patch Update (CPU) from January 2011 which addresses CVE-2010-4435
  2. Alternatively, disable the CDE Calendar Manager Service Daemon (rpc.cmsd) if not required by running: svcs -d svc:/network/rpc/cmsd
  3. To disable rpc.cmsd completely: svcadm disable svc:/network/rpc/cmsd
  4. Verify the service is disabled: svcs svc:/network/rpc/cmsd
  5. Ensure firewall rules block RPC port 32767/tcp if rpc.cmsd cannot be disabled
Caveat Old CDE calendar applications will no longer function if rpc.cmsd service is disabled; ensure no business-critical CDE calendar dependencies exist before disabling

No vendor fix exists Sunos has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
