Debian LTS Advisory ([SECURITY] [DLA 1369-1] linux security update)

Published: 2018-05-03 22:00:00
CVE Author: NIST National Vulnerability Database

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

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Affected Versions:
linux on Debian Linux

Recommendations:
For Debian 7 'Wheezy', these problems have been fixed in version 3.2.101-1. This version also includes bug fixes from upstream versions up to and including 3.2.101. It also fixes a regression in the procfs hidepid option in the previous version (Debian bug #887106). We recommend that you upgrade your linux Linux Distribution Packages.

Summary:
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-0861 Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice. CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the 'retpoline' compiler feature which allows indirect branches to be isolated from speculative execution. CVE-2017-13166 A bug in the 32-bit compatibility layer of the v4l2 ioctl handling code has been found. Memory protections ensuring user-provided buffers always point to userland memory were disabled, allowing destination addresses to be in kernel space. On a 64-bit kernel (amd64 flavour) a local user with access to a suitable video device can exploit this to overwrite kernel memory, leading to privilege escalation. Description truncated. Please see the references for more information.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

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".
