CVE-ID : CVE-2020-8927
Package : brotli
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-1230
The package brotli before version 1.0.9-1 is vulnerable to denial of
service.
Upgrade to 1.0.9-1.
The problem has been fixed upstream in version 1.0.9.
None.
A buffer overflow exists in the Brotli library < 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.
A remote attacker might be able to cause a crash via crafted content.
