pyasn1: Uncontrolled resource consumption when converting decoded REAL values...
PT-2026-58107
Name of the Vulnerable Software and Affected Versions pyasn1 versions prior to 0.6.4 Description The univ.Real type converts its mantissa, base, and exponent value to a Python float using exact big-integer exponentiation. A BER, CER, or DER encoded REAL value containing a very large exponent can...
pyasn1: pyasn1: Denial of Service via crafted ASN.1 REAL values
A remote attacker can exploit this by providing specially crafted BER/CER/DER-encoded ASN.1 data with a large exponent in the REAL value. When the application subsequently prints, logs, compares, or performs arithmetic on the decoded value, this can cause excessive CPU and memory consumption,...
RHEL 9 : libtasn1 (RHSA-2026:28253)
The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:28253 advisory. A library that provides Abstract Syntax Notation One ASN.1, as specified by the X.680 ITU-T recommendation parsing and structures management, and...
ALSA-2026:28253 Low: libtasn1 security update
A library that provides Abstract Syntax Notation One ASN.1, as specified by the X.680 ITU-T recommendation parsing and structures management, and Distinguished Encoding Rules DER, as per X.690 encoding and decoding functions. Security Fixes: libtasn1: libtasn1: Denial of Service via stack-based...

EulerOS Virtualization 2.13.0 : python-pyasn1 (EulerOS-SA-2026-2416)
According to the versions of the python-pyasn1 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : 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...
ASN.1-Compliant CLDAP Validator
This Metasploit module implements a production-grade CLDAP LDAP over UDP validator that strictly follows ASN.1 BER encoding rules. It builds compliant LDAP search requests for Netlogon verification using carefully structured BER encoders for integers, strings, sequences, and filters. It can be us...
OpenSSL 缓冲区错误漏洞
OpenSSL is an open-source encryption library developed by the OpenSSL team that enables secure implementation of Secure Sockets Layer SSLv2/v3 and Secure Transport Layer TLSv1 protocols. This product supports various encryption algorithms, including symmetric ciphers, hash algorithms, and secure...
CVE-2026-43988
Vanetza is an open-source implementation of the ETSI C-ITS protocol suite. In 26.02 and earlier, a denial-of-service vulnerability was identified in the ASN.1/OER parsing pipeline of Vanetza. When processing malformed network packets containing corrupted ASN.1/OER structures e.g., invalid length...
CVE-2026-45615
mouse07410/asn1c is an ASN.1 compiler. In 1.4 and earlier, a memory safety vulnerability was identified in the OER decoding skeleton files generated by asn1c specifically INTEGERoer.c. When parsing a maliciously crafted, zero-length OER payload for a variable-length, non-negative INTEGER type, th...
pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion
An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE 0x30 or SET 0x31 tags with Indefinite Length 0x80 markers. Thi...

FlexRIC 安全漏洞
FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability stems from a failure in ASN.1 PER decoding, resulting in a reachable assertion in e2apcreatepdu. This could allow unauthorized remote attackers ...
CVE-2026-44905
Vanetza is an open-source implementation of the ETSI C-ITS protocol suite. In 26.02 and earlier, a denial-of-service vulnerability was identified in the cryptographic verification pipeline of Vanetza. When processing incoming V2X messages, the ASN.1 decoder accepts the structure as syntactically...
Vanetza 安全漏洞
Vanetza is an open-source implementation of a vehicle communication protocol suite developed by Raphael Riebl. Versions of Vanetza prior to 26.02 contained a security vulnerability. This vulnerability occurred when processing malformed network packets in the ASN.1/OER parsing pipeline, where the...
