Amazon Linux AMI : glibc (ALAS-2024-1930)

high Nessus Plugin ID 194723

Language:

Synopsis

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

Description

The version of glibc installed on the remote host is prior to 2.17-324.190. It is, therefore, affected by a vulnerability as referenced in the ALAS-2024-1930 advisory.

 - The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable. (CVE-2024-2961)

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.
