GHSA-M4P7-R5RC-7G4J pyasn1 BER/CER/DER decoder denial of service via unbounded long-form tag IDs

Impact The BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets in a loop with no upper bound on the size of the tag ID. A crafted input can force the decoder to build an arbitrarily large integer, with CPU cost growing quadratically in input size...

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...

CVE-2026-59885

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER, CER, and DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs, so a small crafted payload containing an OID with many arcs consumes excessive CPU per decode call and c...

GHSA-6JMW-6MXW-W4JC BER/CER/DER decoder panics on invalid input

NLnet Labs’ bcder library up to and including version 0.7.2 panics while decoding certain invalid input data rather than rejecting the data with an error. This can affect both the actual decoding stage as well as accessing content of types that utilized delayed decoding...

CVE-2023-39914 BER/CER/DER decoder panics on invalid input
