CVE-2026-40253
openCryptoki (PKCS#11 library) is affected in versions 3.26.0 and earlier due to BER/DER decoding in the shared asn1.c lacking a buffer length parameter and trusting BER lengths, enabling out-of-bounds reads when malformed BER objects are provided via C_CreateObject, C_UnwrapKey, token loading, o...
CVE-2026-40253 openCryptoki: Memory safety vulnerabilities in BER/DER decoders in asn1.c
openCryptoki is a PKCS11 library and provides tooling for Linux and AIX. In versions 3.26.0 and below, the BER/DER decoding functions in the shared common library asn1.c accept a raw pointer but no buffer length parameter, and trust attacker-controlled BER length fields without validating them...

Amazon Linux 2023 : python3-pyasn1, python3-pyasn1-modules (ALAS2023-2026-1538)
It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1538 advisory. 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...
MGASA-2026-0094 Updated squid packages fix security vulnerabilities
Squid mishandles ASN.1 encoding of long SNMP OIDs. This occurs in asnbuildobjid in lib/snmplib/asn1.c. CVE-2025-59362 Squid vulnerable to information disclosure via authentication credential leakage in error handling. CVE-2025-62168 Squid vulnerable to Denial of Service in ICP Request handling...
encoding/asn1: Parsing DER payload can cause memory exhaustion in encoding/asn1
A memory exhaustion flaw has been discovered in the golang encoding/asn1 module. Within parseSequenceOf, reflect.MakeSlice is being used to pre-allocate a slice that is needed in order to fully validate the given DER payload. The size of the slice allocated are also multiple times larger than the...
CVE-2026-5188
An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name SAN extension of X.509 certificates. A malformed certificate can specify an entry length larger than the enclosing sequence, causing the internal length counter to wrap during parsing. This results in incorrect...

CVE-2026-5187
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...
openssl: OpenSSL: Denial of Service via type confusion in PKCS#7 signature verification
A flaw was found in OpenSSL. This type confusion vulnerability allows a remote attacker to cause a denial of service DoS by providing specially crafted PKCS7 data to an application that performs signature verification. The vulnerability occurs because the application accesses an ASN1TYPE union...
openssl: OpenSSL: Denial of Service via malformed TimeStamp Response
A flaw was found in OpenSSL. A type confusion vulnerability exists in the TimeStamp Response verification code, where an ASN1TYPE union member is accessed without proper type validation. A remote attacker can exploit this by providing a malformed TimeStamp Response to an application that verifies...
