Amazon Linux AMI : curl (ALAS-2020-1411)

high Nessus Plugin ID 139091

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 7.61.1-12.94. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1411 advisory.

 This issue only affects the 'curl' command line utility. Additionally, this is only an issue when using the '-J' (with the '-O' option) and '-i' command line options combined. In most cases, there is nothing to gain for a local attacker here: the curl command line utility is likely running with the same privileges as the user, and thus the user can already overwrite all the files curl could overwrite. However, a local user will have to call curl with the '-J' and '-i' command line options while requesting content from a malicious server, which then opens up an opportunity for the malicious server to overwrite local files.
 (CVE-2020-8177)

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.
