EulerOS 2.0 SP13 : kata-containers (EulerOS-SA-2026-1243)

high Nessus Plugin ID 301619

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 A denial-of-service vulnerability exists in github.com/sirupsen/logrus when using Entry.Writer() to log a single-line payload larger than 64KB without newline characters. Due to limitations in the internal bufio.Scanner, the read fails with 'token too long' and the writer pipe is closed, leaving Writer() unusable and causing application unavailability (DoS). This affects versions 1.8.3, 1.9.0, and 1.9.2.
 The issue is fixed in 1.8.3, 1.9.1, and 1.9.3+, where the input is chunked and the writer continues to function even if an error is logged.(CVE-2025-65637)

Tenable has extracted the preceding description block directly from the EulerOS kata-containers 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 kata-containers packages.
