Debian Security Advisory DSA 3290-1 (linux - security update)

Published: 2015-06-17 22:00:00
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/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 3.2.68-1+deb7u2. For the stable distribution (jessie), these problems were fixed in version 3.16.7-ckt11-1 or earlier, except for CVE-2015-4167 which will be fixed later. 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 leaks or data corruption. CVE-2015-1805 Red Hat discovered that the pipe iovec read and write implementations may iterate over the iovec twice but will modify the iovec such that the second iteration accesses the wrong memory. A local user could use this flaw to crash the system or possibly for privilege escalation. This may also result in data corruption and information leaks in pipes between non-malicious processes. CVE-2015-3636 Wen Xu and wushi of KeenTeam discovered that users allowed to create ping sockets can use them to crash the system and, on 32-bit architectures, for privilege escalation. However, by default, no users on a Debian system have access to ping sockets. CVE-2015-4167 Carl Henrik Lunde discovered that the UDF implementation is missing a necessary length checks. A local user that can mount devices could use this flaw to crash the system.

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".
