CVE Author: NIST National Vulnerability Database

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

Summary:
The remote host is missing an update for the 'linux' Linux Distribution Package(s) announced via the DSA-2068-1 advisory.

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

Technical Details:
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service, or information leak. CVE-2019-2215 The syzkaller tool discovered a use-after-free vulnerability in the Android binder driver. A local user on a system with this driver enabled could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. However, this driver is not enabled on Debian Linux Distribution Packaged kernels. CVE-2019-10220 Various developers and researchers found that if a crafted file- system or malicious file server presented a directory with filenames including a '/' character, this could confuse and possibly defeat security checks in applications that read the directory. The kernel will now return an error when reading such a directory, rather than passing the invalid filenames on to user-space. CVE-2019-14895, CVE-2019-14901 ADLab of Venustech discovered potential heap buffer overflows in the mwifiex wifi driver. On systems using this driver, a malicious Wireless Access Point or adhoc/P2P peer could use these to cause a denial of service (memory corruption or crash) or possibly for remote code execution. CVE-2019-14896, CVE-2019-14897 ADLab of Venustech discovered potential heap and stack buffer overflows in the libertas wifi driver. On systems using this driver, a malicious Wireless Access Point or adhoc/P2P peer could use these to cause a denial of service (memory corruption or crash) or possibly for remote code execution. CVE-2019-15098 Hui Peng and Mathias Payer reported that the ath6kl wifi driver did not properly validate USB descriptors, which could lead to a null pointer derefernce. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops). CVE-2019-15217 The syzkaller tool discovered that the zr364xx mdia driver did not correctly handle devices without a product name string, which could lead to a null pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops). CVE-2019-15291 The syzkaller tool discovered that the b2c2-flexcop-usb media driver did not properly validate USB descriptors, which could lead to a null pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops). CVE-2019-15505 The syzkaller tool discovered that the technisat-usb2 media driver did not properly validate incoming IR packets, which could lead to a heap buffer over-read. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops) or to read sensitive information from kernel memory. ... Description truncated. Please see the references for more information.

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".
