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
Use-after-free vulnerability in iChat Server in Apple Mac OS X Server 10.5.8 allows remote authenticated users to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors.

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
How this class of weakness works · CWE-399

A legacy NVD category grouping weaknesses in how resources — memory, file handles, connections — are allocated, used, and released. It gathers leaks, exhaustion, and lifecycle bugs under one label rather than naming a single flaw. The fix depends on the specific resource issue, generally pairing acquisition with release and bounding what any request can consume.
