Rocky Linux 8 : brotli (RLSA-2021:1702)
medium Nessus Plugin ID 184629
Synopsis
The remote Rocky Linux host is missing a security update.Description
The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2021:1702 advisory.- 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. (CVE-2020-8927)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
