Amazon Linux AMI : curl (ALAS-2021-1525)

low Nessus Plugin ID 153160

Language:

Synopsis

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

Description

The version of curl installed on the remote host is prior to 7.61.1-12.99. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1525 advisory.

 A flaw was found in libcurl in the way libcurl handles previously used connections without accounting for 'issuer cert' and comparing the involved paths case-insensitively. This flaw allows libcurl to use the wrong connection. The highest threat from this vulnerability is to confidentiality. (CVE-2021-22924)

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 curl' to update your system.
