Amazon Linux 2 : libsndfile (ALAS-2023-1998)

high Nessus Plugin ID 173237

Language:

Synopsis

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

Description

The version of libsndfile installed on the remote host is prior to 1.0.25-12. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-1998 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)

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 'yum update libsndfile' to update your system.
