Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing a security update.

Description

According to the version of the brotli package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

- 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected brotli package.
