Synopsis
The remote machine is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:- An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an
__blk_drain_queue() use-after-free because a certain error case is mishandled. (CVE-2018-20856)
- A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiex_uap_parse_tail_ies function in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other consequences.
(CVE-2019-10126)
- A vulnerability was found in Linux kernel's, versions up to 3.10, implementation of overlayfs. An attacker with local access can create a denial of service situation via NULL pointer dereference in ovl_posix_acl_create function in fs/overlayfs/dir.c. This can allow attackers with ability to create directories on overlayfs to crash the kernel creating a denial of service (DOS).
(CVE-2019-10140)
- A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (CVE-2019-3846)
- The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute- force attacks (aka KNOB) that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.
(CVE-2019-9506)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade the vulnerable CGSL kernel packages. Note that updated packages may not be available yet. Please contact ZTE for more information.See Also
