Amazon Linux 2 : glibc (ALAS-2021-1599)

medium Nessus Plugin ID 146625
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of glibc installed on the remote host is prior to 2.26-40. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1599 advisory.

- The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi- byte input sequences in the EUC-KR encoding, may have a buffer over-read. (CVE-2019-25013)

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 glibc' to update your system.
