CVE-2022-24294: 
Python vulnerability analysis and mitigation

A regular expression used in Apache MXNet (incubating) was identified as vulnerable to a potential denial-of-service attack through excessive resource consumption. The vulnerability, tracked as CVE-2022-24294, affects Apache MXNet versions prior to 1.9.1. The issue was discovered and reported by Dwi Siswanto (OpenWall, NVD).

The vulnerability exists in the RTC (Runtime Compilation) Module of Apache MXNet. The issue manifests when loading a model that contains a specially crafted operator name, which triggers excessive resource consumption during regular expression evaluation. The severity of this vulnerability is classified as low (OpenWall).

When exploited, this vulnerability can lead to a denial-of-service condition through excessive resource consumption during the regular expression evaluation process. The impact is limited to the processing of models with specifically crafted operator names (OpenWall).

The vulnerability can be triggered when loading a model in Apache MXNet that contains a specially crafted operator name. The exploitation requires the ability to manipulate the operator names within a model that will be processed by the affected MXNet installation (OpenWall).

Users depending on MXNet 1.x are advised to upgrade to MXNet version 1.9.1 or later (but less than version 2). This upgrade addresses the regular expression vulnerability and prevents potential denial-of-service attacks (OpenWall).
