encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...

openssl: OpenSSL: Heap buffer over-read in ASN.1 decoding can lead to denial of service or information disclosure.

A flaw was found in OpenSSL. An integer truncation vulnerability in the ASN.1 decoder can occur when processing a crafted DER-encoded ASN.1 structure with a primitive element exceeding 2 gigabytes. A remote attacker could exploit this to cause a heap buffer over-read. This may lead to an...

USN-8712-1: pyasn1 vulnerabilities

It was discovered that pyasn1 did not properly bound the size of long-form tag identifiers when parsing BER, CER, or DER encoded data. An attacker could possibly use this issue to cause applications decoding untrusted ASN.1 data to consume excessive CPU resources, resulting in a denial of service...

CVE-2026-80544

A flaw was found in the Linux kernel's s390/zcrypt component. The zcryptmsgtype6sendep11cprb function, responsible for handling EP11 CPRB Coprocessor Request Block domains, uses fragile struct overlays. This approach lacks proper ASN.1 Abstract Syntax Notation One encoding validation and bounds...

CVE-2026-13506

A flaw was found in Bouncy Castle for Java. A remote attacker could exploit a vulnerability related to how the software processes lazy ASN.1 sequences, which can reset an internal nesting-depth guard. This issue could lead to a Denial of Service DoS, making the affected system or application...
