CVE-2024-1023
Full vulnerability record from the local CVENow database.
Description
A vulnerability in the Eclipse Vert.x toolkit results in a memory leak due to using Netty FastThreadLocal data structures. Specifically, when the Vert.x HTTP client establishes connections to different hosts, triggering the memory leak. The leak can be accelerated with intimate runtime knowledge, allowing an attacker to exploit this vulnerability. For instance, a server accepting arbitrary internet addresses could serve as an attack vector by connecting to these addresses, thereby accelerating the memory leak.

"value": "Una vulnerabilidad en el kit de herramientas Eclipse Vert.x provoca una pérdida de memoria debido al uso de estructuras de datos Netty FastThreadLocal. Específicamente, cuando el cliente HTTP Vert.x establece conexiones con diferentes hosts, lo que desencadena la pérdida de memoria. La filtración se puede acelerar con un conocimiento íntimo del tiempo de ejecución, lo que permite a un atacante explotar esta vulnerabilidad. Por ejemplo, un servidor que acepte direcciones de Internet arbitrarias podría servir como vector de ataque al conectarse a estas direcciones, acelerando así la pérdida de memoria."
