high Nessus Plugin ID 304593

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of rust installed on the remote host is prior to 1.93.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3225 advisory.

 Decompressing invalid LZ4 data can leak data from uninitialized memory, or can leak content from previous decompression operations when reusing an output buffer. (CVE-2026-32829)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update rust' or or 'yum update --advisory ALAS2-2026-3225' to update your system.
