Huawei EulerOS: Security Advisory for kernel (EulerOS-SA-2019-1204)

Published: 2020-01-23 11:34:28
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:L/Au:N/C:C/I:C/A:C

Summary:
The remote host is missing an update for the Huawei EulerOS 'kernel' Linux Distribution Package(s) announced via the EulerOS-SA-2019-1204 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
A security flaw was found in the Linux kernel in drivers/tty/n_tty.c which allows local attackers (ones who are able to access pseudo terminals) to lock them up and block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ handler.CVE-2018-18386 The Linux kernel was found vulnerable to an integer overflow in the drivers/video/fbdev/uvesafb.c:uvesafb_setcmap() function. The vulnerability could result in local attackers being able to crash the kernel or potentially elevate privileges.CVE-2018-13406 The vsock_stream_sendmsg function in net/vmw_vsock/af_vsock.c in the Linux kernel before 3.9-rc7 does not initialize a certain length variable, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call.CVE-2013-3237 The llc_ui_recvmsg function in net/llc/af_llc.c in the Linux kernel before 3.9-rc7 does not initialize a certain length variable, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call.CVE-2013-3231 The crypto API in the Linux kernel through 3.9-rc8 does not initialize certain length variables, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call, related to the hash_recvmsg function in crypto/algif_hash.c and the skcipher_recvmsg function in crypto/algif_skcipher.c.CVE-2013-3076 Integer overflow in the snd_compr_allocate_buffer function in sound/core/compress_offload.c in the ALSA subsystem in the Linux kernel before 3.6-rc6-next-20120917 allows local users to cause a denial of service (insufficient memory allocation) or possibly have unspecified other impact via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl call.CVE-2012-6703

Affected Versions:
'kernel' Linux Distribution Package(s) on Huawei EulerOS Virtualization 2.5.4.

Recommendations:
Please install the updated Linux Distribution Package(s).

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
