Vulnerabilidades

An issue was discovered in Esoteric YamlBeans through 1.15. It allows untrusted deserialisation to Java classes by default, where the data and class are controlled by the author of the YAML document being processed.

An issue was discovered in Esoteric YamlBeans through 1.15. A crafted YAML document is able perform am XML Entity Expansion attack against YamlBeans YamlReader. By exploiting the Anchor feature in YAML, it is possible to generate a small YAML document that, when read, is expanded to a large size, causing CPU and…

Uncaught Exception in GitHub repository eemeli/yaml prior to 2.0.0-5.

Parsing malicious or large YAML documents can consume excessive amounts of CPU or memory.

Due to unbounded alias chasing, a maliciously crafted YAML file can cause the system to consume significant system resources. If parsing user input, this may be used as a denial of service vector.

SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization. Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using SnakeYaml's SafeConsturctor when parsing untrusted content to restrict deserialization. We recommend…

Those using Snakeyaml to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stack overflow. This effect may support a denial of service attack.

The d8s-yaml package for Python, as distributed on PyPI, included a potential code-execution backdoor inserted by a third party. The backdoor is the democritus-file-system package. The affected version is 0.1.0.

Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stack-overflow.

Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow.

The package org.yaml:snakeyaml from 0 and before 1.31 are vulnerable to Denial of Service (DoS) due missing to nested depth limitation for collections.

An issue in the Unmarshal function in Go-Yaml v3 causes the program to crash when attempting to deserialize invalid input.

A vulnerability was discovered in the PyYAML library in versions before 5.4, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this…

Jenkins Yaml Axis Plugin 0.2.0 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerability.

A vulnerability was discovered in the PyYAML library in versions before 5.3.1, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this…

JYaml through 1.3 allows remote code execution during deserialization of a malicious payload through the load() function. NOTE: this is a discontinued product.

In ruamel.yaml through 0.16.7, the load method allows remote code execution if the application calls this method with an untrusted argument. In other words, this issue affects developers who are unaware of the need to use methods such as safe_load in these use cases.

PyYAML 5.1 through 5.1.2 has insufficient restrictions on the load and load_all functions because of a class deserialization issue, e.g., Popen is a class in the subprocess module. NOTE: this issue exists because of an incomplete fix for CVE-2017-18342.

The Alias feature in SnakeYAML before 1.26 allows entity expansion during a load operation, a related issue to CVE-2003-1564.

An issue was discovered in the yaml-rust crate before 0.4.1 for Rust. There is uncontrolled recursion during deserialization.

yaml-rust 0.4.0 and earlier is affected by: Uncontrolled Recursion. The impact is: Denial of service by impossible to catch abort. The component is: YamlLoader::load_from_str function. The attack vector is: Parsing of a malicious YAML document. The fixed version is: 0.4.1 and later.

serde serde_yaml 0.6.0 to 0.8.3 is affected by: Uncontrolled Recursion. The impact is: Denial of service by aborting. The component is: from_* functions (all deserialization functions). The attack vector is: Parsing a malicious YAML file. The fixed version is: 0.8.4 and later.

An issue was discovered in singledocparser.cpp in yaml-cpp (aka LibYaml-C++) 0.6.2. Stack Exhaustion occurs in YAML::SingleDocParser, and there is a stack consumption problem caused by recursive stack frames: HandleCompactMap, HandleMap, HandleFlowSequence, HandleSequence, HandleNode. Remote attackers could leverage…
