FKIE_CVE-2025-64508

Vulnerability from fkie_nvd - Published: 2025-11-10 22:15 - Updated: 2025-11-12 16:19
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
Bugsink is a self-hosted error tracking tool. In versions prior to 2.0.5, brotli "bombs" (highly compressed brotli streams, such as many zeros) can be sent to the server. Since the server will attempt to decompress these streams before applying various maximums, this can lead to exhaustion of the available memory and thus a Denial of Service. This can be done if the `DSN` is known, which it is in many common setups (JavaScript, Mobile Apps). The issue is patched in Bugsink version `2.0.5`. The vulnerability is similar to, but distinct from, another brotli-related problem in Bugsink, GHSA-rrx3-2x4g-mq2h/CVE-2025-64509.

En versiones anteriores a la 2.0.5, se pueden enviar \u0027bombas\u0027 brotli (flujos brotli altamente comprimidos, como muchos ceros) al servidor. Dado que el servidor intentar\u00e1 descomprimir estos flujos antes de aplicar varios m\u00e1ximos, esto puede llevar al agotamiento de la memoria disponible y, por lo tanto, a una Denegaci\u00f3n de Servicio. Esto se puede lograr si se conoce el \u0027DSN\u0027, lo cual ocurre en muchas configuraciones comunes (JavaScript, aplicaciones m\u00f3viles). El problema est\u00e1 parcheado en la versi\u00f3n \u00272.0.5\u0027 de Bugsink.
