SharpCompress is vulnerable to Denial of Service (DoS)
48
Medium Risk
This Affects:
SharpCompressTL;DR
The tar reader could keep requesting further entries even when the underlying stream could no longer supply a complete header for the next record, which allowed iteration to spin without making forward progress on corrupted or truncated input. The archive facade now treats a failed header read as a terminal archive error instead of continuing the enumeration loop. Regression tests cover advancing the reader after a broken tail so callers get a deterministic failure instead of a hang.
