Amazon Linux 2 : qemu (ALAS-2023-2207)

medium Nessus Plugin ID 180085

Language:

Synopsis

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

Description

The version of qemu installed on the remote host is prior to 3.1.0-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2207 advisory.

 A flaw was found in the QEMU virtual crypto device while handling data encryption/decryption requests in virtio_crypto_handle_sym_req. There is no check for the value of `src_len` and `dst_len` in virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow when the two values differ.
 (CVE-2023-3180)

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 qemu' to update your system.
