Amazon Linux 2 : rust (ALAS-2026-4071)

high Nessus Plugin ID 377937

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 1.98.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-4071 advisory.

gitoxide gix-packetline versions before 0.21.5 contain a panic vulnerability in the TextRef implementation that occurs when processing side-band packet lines with empty payloads. A malicious Git server can send a crafted side-band packet to trigger an index out of bounds panic, aborting the client process during fetch operations without authentication. (CVE-2026-82250)

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 ALAS2-2026-4071' to update your system.
