Vulnerabilidades

cbor2 provides encoding and decoding for the Concise Binary Object Representation (CBOR) serialization format. Versions prior to 5.9.0 are vulnerable to a Denial of Service (DoS) attack caused by uncontrolled recursion when decoding deeply nested CBOR structures. This vulnerability affects both the pure Python…

cbor2 provides encoding and decoding for the Concise Binary Object Representation (CBOR) serialization format. Starting in version 3.0.0 and prior to version 5.8.0, whhen a CBORDecoder instance is reused across multiple decode operations, values marked with the shareable tag (28) persist in memory and can be accessed…

Multiple vulnerabilities exist in cbor2 through version 5.7.0 in the decode_definite_long_string() function of the C extension decoder (source/decoder.c): (1) Integer Underflow Leading to Out-of-Bounds Read (CWE-191, CWE-125): An incorrect variable reference and missing state reset in the chunk processing loop causes…

Uncontrolled recursion for some TinyCBOR libraries maintained by Intel(R) before version 0.6.1 may allow an authenticated user to potentially enable escalation of privilege via local access.

Uncontrolled recursion for some TinyCBOR libraries maintained by Intel(R) before version 0.6.1 may allow an authenticated user to potentially enable denial of service via local access.

cbor2 provides encoding and decoding for the Concise Binary Object Representation (CBOR) (RFC 8949) serialization format. Starting in version 5.5.1 and prior to version 5.6.2, an attacker can crash a service using cbor2 to parse a CBOR binary by sending a long enough object. Version 5.6.2 contains a patch for this…

Inefficient algorithmic complexity in DecodeFromBytes function in com.upokecenter.cbor Java implementation of Concise Binary Object Representation (CBOR) versions 4.0.0 to 4.5.1 allows an attacker to cause a denial of service by passing a maliciously crafted input. Depending on an application's use of this library,…

PeterO.Cbor versions 4.0.0 through 4.5.0 are vulnerable to a denial of service vulnerability. An attacker may trigger the denial of service condition by providing crafted data to the DecodeFromBytes or other decoding mechanisms in PeterO.Cbor. Depending on the usage of the library, an unauthenticated and remote…

An issue was discovered in the serde_cbor crate before 0.10.2 for Rust. The CBOR deserializer can cause stack consumption via nested semantic tags.

A memory corruption vulnerability in Objective Open CBOR Run-time (oocborrt) in versions before 2020-08-12 could allow an attacker to execute code via crafted Concise Binary Object Representation (CBOR) input to the cbor2json decoder. An uncaught error while decoding CBOR Major Type 3 text strings leads to the use of…
