medium Nessus Plugin ID 173280

Synopsis

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

Description

The version of tar installed on the remote host is prior to 1.26-31.23. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1704 advisory.

- GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has not been demonstrated. The issue occurs in from_header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters.

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 tar' to update your system.
