CVE-2008-2943 is a medium-severity use after free vulnerability in n/a, published on 30 Jun 2008. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Double free vulnerability in IBM Tivoli Directory Server (TDS) 6.1.0.0 through 6.1.0.15 allows remote authenticated administrators to cause a denial of service (ABEND) and possibly execute arbitrary code by using ldapadd to attempt to create a duplicate ibm-globalAdminGroup LDAP database entry.  NOTE: the vendor states "There is no real risk of a vulnerability," although there are likely scenarios in which a user is allowed to make administrative LDAP requests but does not have the privileges to stop the server.

Weakness: CWE-399

Check this codebase for CVE-2008-2943 and fix it if it is affected.

What it is: CVE-2008-2943 is a medium-severity use after free vulnerability in n/a, published on 30 Jun 2008. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2008-2943 exists.

Affected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
