Synopsis

The remote Alibaba Cloud Linux host is missing one or more security updates.

Description

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2025:0171 advisory.

 Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

 CVE-2025-8677:
 A vulnerability was found in BIND 9 resolvers, where processing malformed DNSKEY records from a specially crafted zone can lead to resource exhaustion, primarily causing excessive CPU utilization. This issue enables a remote, unauthenticated attacker to degrade resolver performance and potentially cause a denial of service (DoS) for legitimate DNS clients.

 CVE-2025-40778:
 Under certain circumstances, BIND is too lenient when accepting records from answers, allowing an attacker to inject forged data into the cache.
 This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1.
