EUVD-2026-51357

The MMS BER decoder contains a boundary-handling flaw in the processing of certain fields within confirmed-request messages. When a crafted BER-encoded element is received over an established MMS session TCP port 102, the decoder may advance its internal read position incorrectly, leading to a he...

EUVD-2026-51342

The MMS BER decoder contains a flaw in decoding fixed-width BER fields boolean/integer: an attacker-supplied length value is not validated, causing a read past the end of a heap buffer. This leads to termination of the MMS service process and a denial-of-service condition...

CVE-2026-59884

A flaw was found in pyasn1, a generic ASN.1 library for Python. The Basic Encoding Rules BER decoder, used by CER and DER codecs, processes long-form tags by accumulating continuation octets without an upper bound. A remote attacker can exploit this by providing a specially crafted input, leading...

python-pyasn1: pyasn1: Denial of Service via crafted BER input

A flaw was found in pyasn1, a generic ASN.1 library for Python. The Basic Encoding Rules BER decoder, used by CER and DER codecs, processes long-form tags by accumulating continuation octets without an upper bound. A remote attacker can exploit this by providing a specially crafted input, leading...

Excessive Iteration

Overview Affected versions of this package are vulnerable to Excessive Iteration via the BER decoder, which is also used by the CER and DER codecs, when parsing long-form tag IDs without an upper bound. An attacker can exhaust system resources and potentially trigger unhandled exceptions by...

CVE-2026-59884

pyasn1 prior to 0.6.4 contains a denial-of-service risk in its BER decoder used by CER/DER codecs: long-form tag IDs can be accumulated without an upper bound, enabling a crafted input to drive CPU usage quadratically and trigger unhandled ValueError paths in Python 3.11+ error formatting. Affect...

openCryptoki: openCryptoki: Information disclosure and Denial of Service via malformed BER-encoded cryptographic objects

A flaw was found in openCryptoki, a PKCS11 Cryptographic Token Interface Standard library. The BER/DER Basic Encoding Rules/Distinguished Encoding Rules decoding functions in the shared common library do not properly validate attacker-controlled length fields against actual buffer boundaries. Thi...

389-ds-base: 389-ds-base: unbounded LDAP controls count in get_ldapmessage_controls_ext() causes CPU and heap amplification (remote DoS)

A flaw was found in 389-ds-base. The getldapmessagecontrolsext function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls...

CLDAP Analyzer with ASN.1 BER Encoding and Basic TLV Response Parser

This Python script implements a CLDAP Connectionless LDAP analyzer that builds and sends LDAP CLDAP discovery requests and parses responses using ASN.1 BER encoding and a basic TLV parser. It constructs a structured LDAP search request including DnsDomain, User, and NtVer filters, sends it over U...

CVE-2026-44378

A flaw was found in Botan, a C++ cryptography library. A remote attacker could exploit this vulnerability by sending specially crafted Basic Encoding Rules BER data with indefinite length encodings. This could cause quadratic behavior in the parser, leading to a denial of service DoS due to...

Inefficient Algorithmic Complexity

Overview Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the BER data parsing process. An attacker can cause excessive resource consumption and service disruption by submitting specially crafted indefinite length encodings. Remediation Upgrade botan to...

CVE-2026-44378 Botan: Quadratic complexity decoding BER indefinite length encodings

Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which...
