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,...

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...

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-2026-51340

The MMS server connection handler contains a flaw in its processing of BER-encoded request data. When an MMS confirmed request PDU containing an extended BER tag is received over an established session, the decoder may advance its internal buffer incorrectly due to a missing bounds check. This...

CVE-2026-65421

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-2026-63550

CVE-2026-43823

A flaw was found in swift-crypto. When an RSA Rivest-Shamir-Adleman public key is initialized from DER Distinguished Encoding Rules or PEM Privacy-Enhanced Mail formatted bytes, and an error occurs during the decoding process, a double-free vulnerability can be triggered. This issue, occurring wh...

CVE-2026-43823

When initializing an RSA public key from DER or PEM bytes throws an error, the EVPPKEY is double-freed: first in the catch block, then in the deinit. This can lead to a crash on future memory allocations. This double-free manifests when BoringSSL cannot decode the public key from the bytes...

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...

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...

UBUNTU-CVE-2026-59884

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets without an upper bound on the tag ID size, allowing a crafted input to force construction of an arbitrarily large integer with C...
