The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities:
A vulnerability was found in the Linux kernel’s Marvell WiFi chip driver. Where, while parsing vendor-specific informational attributes, an attacker on the same WiFi physical network segment could cause a system crash, resulting in a denial of service, or potentially execute arbitrary code. This flaw affects the network interface at the most basic level meaning the attacker only needs to affiliate with the same network device as the vulnerable system to create an attack path.
(CVE-2019-14816)
A heap-based buffer overflow was discovered in the Linux kernel’s Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895)
No description is available for this CVE.
(CVE-2019-14898)
A heap overflow flaw was found in the Linux kernel’s Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system. (CVE-2019-14901)
A vulnerability was found in the Linux kernel’s generic WiFi ESSID handling implementation. The flaw allows a system to join a wireless network where the ESSID is longer than the maximum length of 32 characters, which can cause the system to crash or execute code.
(CVE-2019-17133)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
