CVE-2022-38751

SnakeYAML is a YAML parser and emitter for the Java Virtual Machine. YAML is a data serialization format designed for human readability and interaction with scripting languages.

Security Fix(es):

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.(CVE-2022-25857)

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.(CVE-2022-38749)

This update for snakeyaml fixes the following issues:

snakeyaml was upgraded to version 1.31:

• CVE-2022-25857: Fixed DoS due missing to nested depth limitation for collections (bsc#1202932).
• CVE-2022-38749: Fixed DoS due to stack overflow in parser (bsc#1202932).
• CVE-2022-38751: Fixed DoS due to parsing of untrusted yaml files (bsc#1203153).
• CVE-2022-38752: Fixed DoS due to stack overflow in parser (bsc#1203154).
• CVE-2022-38750: Fixed DoS due to parsing of untrusted yaml files (bsc#1203158).
• CVE-2020-13936: Fixed arbitrary code execution when attacker is able to modify templates (bsc#1183360).

It was discovered that SnakeYAML did not limit the maximal nested depth for collections when parsing YAML data. If a user or automated system were tricked into opening a specially crafted YAML file, an attacker could possibly use this issue to cause applications using SnakeYAML to crash, resulting in a denial of service. (CVE-2022-25857, CVE-2022-38749, CVE-2022-38750)
