EulerOS 2.0 SP12 : brotli (EulerOS-SA-2026-1083)

high Nessus Plugin ID 284781

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the brotli package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 Scrapy versions up to 2.13.2 are vulnerable to a denial of service (DoS) attack due to a flaw in its brotli decompression implementation. The protection mechanism against decompression bombs fails to mitigate the brotli variant, allowing remote servers to crash clients with less than 80GB of available memory. This occurs because brotli can achieve extremely high compression ratios for zero-filled data, leading to excessive memory consumption during decompression.(CVE-2025-6176)

Tenable has extracted the preceding description block directly from the EulerOS brotli security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected brotli packages.
