CVE-2024-29370
Description
A flaw was found in python-jose. This vulnerability allows an attacker to cause a Denial-of-Service (DoS) condition by crafting a malicious JSON Web Encryption (JWE) token with an exceptionally high compression ratio, leading to significant memory allocation and processing time during decompression.
Statement
This vulnerability is rated Moderate for Red Hat products as it allows an attacker to cause a Denial-of-Service (DoS) by crafting a malicious JSON Web Encryption (JWE) token. When processed by applications utilizing python-jose, this token can lead to excessive memory allocation and processing time during decompression. This affects Red Hat Ansible Automation Platform, OpenShift Lightspeed, Red Hat OpenShift AI, and other services that use python-jose for JWE token handling.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
