Amazon Linux 2 : libguestfs-winsupport (ALAS-2020-1522)

high Nessus Plugin ID 141945

Synopsis

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

Description

The version of libguestfs-winsupport installed on the remote host is prior to 7.2-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1522 advisory.

An integer underflow issue exists in ntfs-3g 2017.3.23. A local attacker could potentially exploit this by running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap buffer overflow, resulting in a crash or the ability to execute arbitrary code. In installations where /bin/ntfs-3g is a setuid-root binary, this could lead to a local escalation of privileges. (CVE-2019-9755)

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 libguestfs-winsupport' to update your system.
