Ubuntu 22.04 LTS : QEMU vulnerabilities (USN-6954-1)

medium Nessus Plugin ID 205391

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6954-1 advisory.

 Markus Frank and Fiona Ebner discovered that QEMU did not properly handle certain memory operations, leading to a NULL pointer dereference. An authenticated user could potentially use this issue to cause a denial of service. (CVE-2023-6683)

 Xiao Lei discovered that QEMU did not properly handle certain memory

 operations when specific features were enabled, which could lead to a stack overflow. An attacker could potentially use this issue to leak sensitive information. (CVE-2023-6693)

 It was discovered that QEMU had an integer underflow vulnerability in

 the TI command, which would result in a buffer overflow. An attacker could potentially use this issue to cause a denial of service.

 (CVE-2024-24474)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
