Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1505 advisory.- In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system. (CVE-2019-14866)
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 cpio' to update your system.See Also
