Linux Distros Unpatched Vulnerability : CVE-2026-59885

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER, CER, and DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time...

JLSEC-2026-714

Two potential heap out-of-bounds write locations existed in DecodeObjectId in wolfcrypt/src/asn.c. First, a bounds check only validates one available slot before writing two OID arc values out0 and out1, enabling a 2-byte out-of-bounds write when outSz equals 1. Second, multiple callers pass...

JLSEC-2026-719

A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wcPKCS7DecryptOri function in wolfcrypt/src/pkcs7.c. When processing a CMS EnvelopedData message containing an OtherRecipientInfo ORI recipient, the function copies an ASN.1-parsed OID into a fixed 32-byte stack buffer...

JLSEC-2026-716 Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA...

Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA certificates, or smaller than is appropriate for the relevant key type, to be accepted by signature verification functions. This could lead to reduced security of ECDSA certificate-based authentication...

Inefficient Algorithmic Complexity

Overview Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the decode process. An attacker can cause excessive CPU consumption and disrupt service availability by submitting specially crafted ASN.1 data containing OBJECT IDENTIFIER or RELATIVE-OID values...

AZL-92430 CVE-2026-59885 affecting package python-pyasn1 for versions less than 0.4.8-3

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER, CER, and DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs, so a small crafted payload containing an OID with many arcs consumes excessive CPU per decode call and c...
