Description

rdiffweb prior to 2.4.8 has no limit in length of root directory names. Allowing users to enter long strings may result in a DOS attack or memory corruption. Version 2.4.8 defines a field limit for username, email, and root directory.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rdiffweb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update rdiffweb to 2.4.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hrj7-f62f-j7x7 is resolved across your whole dependency graph.

  3. Workarounds

    Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.
