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
Unknown vulnerability in the AUTH_DES authentication for RPC in Solaris 2.5.1, 2.6, and 7, SGI IRIX 6.5 to 6.5.19f, and possibly other platforms, allows remote attackers to gain privileges.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix Moderate confidence

Upgrade to supported OS versions: Solaris 10 or later, or IRIX 6.5.30 (if available) or migrate to a supported operating system. Note: These are legacy systems with no further vendor support.

  1. 1. Identify all systems running the affected Solaris (2.5.1, 2.6, 7.0) or IRIX (6.5.x) versions with RPC services enabled.
  2. 2. For SGI IRIX systems, download and apply the vendor patch from ftp://patches.sgi.com/support/free/security/advisories/20030402-01-P following SGI patch installation procedures.
  3. 3. For Solaris systems, check SunSolve (sunsolve.sun.com) for available patches for this vulnerability (CVE-2002-1584) and apply all recommended security patches.
  4. 4. If vendor patches are unavailable or systems cannot be patched, disable the AUTH_DES authentication mechanism in the RPC services (rpc.nisd, rpcbind, etc.) by modifying /etc/rc3.d/S71rpc or equivalent startup scripts.
  5. 5. Alternatively, disable or block RPC services at the network firewall level if they are not required for business operations.
  6. 6. Restrict network access to any remaining RPC services to trusted hosts only using TCP wrappers (/etc/hosts.allow, /etc/hosts.deny) or firewall rules.
Caveat Upgrading from Solaris 2.x/7.x to Solaris 10+ will require significant application re-testing and may require 32-bit to 64-bit application recompilation. IRIX upgrade paths are extremely limited as SGI discontinued IRIX support.
