Azure Linux 3.0 Security Update: qemu (CVE-2024-3447)

medium Nessus Plugin ID 235441

Language:

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of qemu installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-3447 advisory.

 - A heap-based buffer overflow was found in the SDHCI device emulation of QEMU. The bug is triggered when both `s->data_count` and the size of `s->fifo_buffer` are set to 0x200, leading to an out-of-bound access.
 A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. (CVE-2024-3447)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
