Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Affected: pyload-ng versions up to and including 0.5.0b3.dev101; no fixed version is listed. The tar extraction code does not check member types and does not pass a safe extraction filter, so a crafted tar archive can make pyLoad create device nodes and FIFOs on disk. An attacker who can submit or trigger extraction of an archive could, when pyLoad runs as root, gain raw disk access and compromise the host. No fix is listed, so the source gives no upgrade path.
