Forge: ASN.1 resource exhaustion via BIT STRING decoding in asn1.fromDer

Summary asn1.fromDer decodes the contents of BIT STRINGs as ASN.1 by default. That decode ignored the maxDepth recursion limit an incomplete fix of CVE-2025-66031 and also decoded nested BIT STRINGs, keeping a full copy of the decoded contents at each level, so small crafted DER or PEM inputs...

TencentOS Server 4: python-pyasn1 (TSSA-2026:1349)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:1349 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities...

SUSE CVE-2026-119196

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.5, constructed BIT STRING decoding repeatedly shifts and copies the complete bit value accumulated from earlier fragments. Attacker-controlled BER or CER input contains many constructed BIT STRING fragments; schema-driven DER also accepts...

Pyasn1 Has Quadratic CPU Consumption In Constructed BIT STRING Decoding

Summary In pyasn1 through 0.6.4, decoding a constructed BIT STRING with many fragments repeatedly shifts and copies the entire value accumulated so far. For fixed-size fragments, CPU time grows quadratically with the encoded input size. An application that passes sufficiently large,...

CVE-2026-119196

A flaw was found in pyasn1. A remote attacker can cause a Denial of Service DoS by sending specially crafted Abstract Syntax Notation One ASN.1 data containing multiple constructed bit string fragments. When decoding these fragments, the library repeatedly copies and shifts accumulated bit data,...
