Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1351 advisory.

When asked to both use a `.netrc` file for credentials and to follow HTTPredirects, curl could leak the password used for the first host to thefollowed-to host under certain circumstances.

This flaw only manifests itself if the netrc file has an entry that matchesthe redirect target hostname but the entry either omits just the password oromits both login and password. (CVE-2024-11053)

When asked to use a `.netrc` file for credentials **and** to follow HTTPredirects, curl could leak the password used for the first host to thefollowed-to host under certain circumstances.

This flaw only manifests itself if the netrc file has a `default` entry thatomits both login and password.
A rare circumstance. (CVE-2025-0167)

curl's code for managing SSH connections when SFTP was done using the wolfSSH powered backend was flawed and missed host verification mechanisms.

This prevents curl from detecting MITM attackers and more. (CVE-2025-10966)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update curl --releasever 2023.10.20260105' or or 'dnf update --advisory ALAS2023-2025-1351 --releasever 2023.10.20260105' to update your system.
