[Security Fix]
- pyasn1 には、無限に再起処理が呼び出され続けてしまう問題が
あるため、リモートの攻撃者により、数千個のネストされた特定のタグ
やマーカーを持つように細工された ASN.1 形式のデータのデコード処理
を介して、サービス拒否攻撃 (メモリ枯渇) を可能とする脆弱性が存在
します。(CVE-2026-30922)

CVE:
CVE-2026-30922
pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.3, the `pyasn1` library is vulnerable to a Denial of Service (DoS) attack caused by uncontrolled recursion when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing thousands of nested `SEQUENCE` (`0x30`) or `SET` (`0x31`) tags with "Indefinite Length" (`0x80`) markers. This forces the decoder to recursively call itself until the Python interpreter crashes with a `RecursionError` or consumes all available memory (OOM), crashing the host application. This is a distinct vulnerability from CVE-2026-23490 (which addressed integer overflows in OID decoding). The fix for CVE-2026-23490 (`MAX_OID_ARC_CONTINUATION_OCTETS`) does not mitigate this recursion issue. Version 0.6.3 fixes this specific issue.
