Debian Security Advisory DSA 3503-1 (linux - security update)

Published: 2016-03-08 07:07:38
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 the oldstable distribution (wheezy), these problems have been fixed in version 3.2.73-2+deb7u3. The oldstable distribution (wheezy) is not affected by CVE-2015-8830 . For the stable distribution (jessie), these problems have been fixed in version 3.16.7-ckt20-1+deb8u4. CVE-2015-7566, CVE-2015-8767 and CVE-2016-0723 were already fixed in DSA-3448-1. CVE-2016-0774 does not affect the stable distribution. 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, information leak or data loss. CVE-2013-4312 Tetsuo Handa discovered that users can use pipes queued on local (Unix) sockets to allocate an unfair share of kernel memory, leading to denial-of-service (resource exhaustion). This issue was previously mitigated for the stable suite by limiting the total number of files queued by each user on local sockets. The new kernel version in both suites includes that mitigation plus limits on the total size of pipe buffers allocated for each user. CVE-2015-7566 Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected. 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".
