Synopsis

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

Description

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5754 advisory.

 - An issue was discovered in the Linux kernel before 5.0.10. There is a use-after-free in the sound subsystem because card disconnection causes certain data structures to be deleted too early. This is related to sound/core/init.c and sound/core/info.c. (CVE-2019-15214)

 - In the Linux kernel before 5.3.4, there is an info-leak bug that can be caused by a malicious USB device in the drivers/media/usb/ttusb-dec/ttusb_dec.c driver, aka CID-a10feaf8c464. (CVE-2019-19533)

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.
