Amazon Linux 2022 : cpio (ALAS2022-2023-263)

high Nessus Plugin ID 170619

Language:

Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2023-263 advisory.

 GNU cpio through 2.13 allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c ds_fgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data.
 (CVE-2021-38185)

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 'dnf update cpio' to update your system.
