CVE-2010-4217
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 · uneditedUse-after-free vulnerability in the proxy server in IBM Tivoli Directory Server (TDS) 6.0.0.x before 6.0.0.8-TIV-ITDS-IF0007 and 6.1.x before 6.1.0-TIV-ITDS-FP0005 allows remote attackers to cause a denial of service (daemon crash) via an unbind request that occurs during a certain search operation.
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.
dbcve analysis · high confidenceA use-after-free vulnerability exists in the proxy server component of IBM Tivoli Directory Server versions 6.0.0.x before 6.0.0.8-TIV-ITDS-IF0007 and 6.1.x before 6.1.0-TIV-ITDS-FP0005. The flaw is triggered when a remote attacker sends an unbind request during an active search operation, causing the server to reference freed memory and crash.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed IBM Tivoli Directory Server versionRun 'idsversion' command or check the version through the IBM Directory Server administration console, or inspect the version file in the installation directory (typically in /opt/ibm/ldap/V6.X/ or the installation root)Affected if Version is 6.0.0.x before fix level 6.0.0.8-TIV-ITDS-IF0007, or version 6.1.x before fix level 6.1.0-TIV-ITDS-FP0005, or matches one of the specific affected builds listed (6.0.0.0, 6.0.0.1, 6.0.0.7, 6.0.0.8, 6.0.0.14, 6.0.0.19, 6.0.0.33, 6.0.0.41, 6.0.0.45, 6.0.0.52, 6.0.0.53, 6.0.0.54)
-
Verify proxy server component is configuredCheck if the LDAP proxy server is enabled by reviewing the IBM Tivoli Directory Server configuration files (ibmslapd.conf or ibmslapd.dcc) in the instance directory, or query the server for proxy functionality using ldapsearch on the administration portAffected if Proxy server functionality is enabled and the server is listening on a proxy port (commonly port 389 or 636)
-
Confirm active search operations can reach the proxyVerify the proxy port is accessible by running 'ldapsearch -h <server> -p <proxy_port> -b <base_dn> -s base objectclass=*' or by checking network listeners with 'netstat -an | grep <port>'Affected if The proxy port is open and accepts LDAP connections
You are affected if you are running a vulnerable version of IBM Tivoli Directory Server (6.0.0.x before 6.0.0.8-TIV-ITDS-IF0007 or 6.1.x before 6.1.0-TIV-ITDS-FP0005) AND the proxy server component is enabled and accessible on the network.

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.
From vendor dataApply the appropriate IBM interim fix (6.0.0.8-TIV-ITDS-IF0007) or fix pack (6.1.0-TIV-ITDS-FP0005) per the IBM Tivoli Directory Server version in use. Consider restricting network access to the directory server proxy port until patching is completed.
