Vulnerability Title
pyasn1 BER/CER/DER decoder denial of service via unbounded long-form tag IDs
Vulnerability Description
pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets without an upper bound on the tag ID size, allowing a crafted input to force construction of an arbitrarily large integer with CPU cost growing quadratically and to trigger unhandled ValueError exceptions in Python 3.11+ error formatting paths. Any application decoding untrusted BER, CER, or DER input is affected. This issue is fixed in version 0.6.4.

Vulnerability Title
pyasn1 资源管理错误漏洞
Vulnerability Description
pyasn1是pyasn1组织开源的一个PythonASN.1库。 pyasn1 0.6.4之前版本存在资源管理错误漏洞,该漏洞源于BER解码器在解析长格式标签时无限制累积连续八位组,可能允许通过特制输入强制构建任意大整数,导致CPU成本二次增长并触发Python 3.11+错误格式化路径中未处理的ValueError异常。
