A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a "one-shot" decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the "streaming" API as opposed to the "one-shot" API, and impose chunk size limits. Se presenta un desbordamiento del búfer en la biblioteca Brotli versiones anteriores a 1.0.8, donde un atacante que controla la longitud de entrada de una petición de descompresión "one-shot" en un script puede desencadenar un bloqueo, que ocurre cuando se copian fragmentos de datos de más de 2 GiB . Se recomienda actualizar su biblioteca de Brotli a la versión 1.0.8 o posterior. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00108.html https://github.com/google/brotli/releases/tag/v1.0.9 https://lists.debian.org/debian-lts-announce/2020/12/msg00003.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/356JOYTWW4BWSZ42SEFLV7NYHL3S3AEH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4TOGTZ2ZWDH662ZNFFSZVL3M5AJXV6JF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-130: Improper Handling of Length Parameter Inconsistency •
