high Nessus Plugin ID 167027

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 ALAS2022-2022-175 advisory.

 - An out-of-bounds read flaw was found in libsndfile's FLAC codec functionality. An attacker who is able to submit a specially crafted file (via tricking a user to open or otherwise) to an application linked with libsndfile and using the FLAC codec, could trigger an out-of-bounds read that would most likely cause a crash but could potentially leak memory information that could be used in further exploitation of other flaws. (CVE-2021-4156)

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 libsndfile --releasever=2022.0.20221102' to update your system.
