medium Nessus Plugin ID 316573
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-2026:0121 advisory.Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:
CVE-2026-32280:
A flaw was found in the Go standard library packages `crypto/x509` and `crypto/tls`. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being performed. This can result in a denial of service (DoS) condition, making the affected system or application unavailable to legitimate users.
CVE-2026-32282:
On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink lying outside the root, so the impact is limited to cases where the target is replaced with a symlink between the check and operation.
CVE-2026-32283:
A flaw was found in the `crypto/tls` package within the Go (golang) standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock, leading to uncontrolled consumption of resources and ultimately a denial of service (DoS).
Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
