Debian Security Advisory DSA 2542-1 (qemu-kvm)
Published: 2012-09-15 08:23:58
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:L/AC:L/Au:N/C:C/I:C/A:C
Technical Details:
Multiple vulnerabilities have been discovered in qemu-kvm, a full
virtualization solution on x86 hardware. The Common Vulnerabilities
and Exposures project identifies the following problems:
CVE-2012-2652:
The snapshot mode of Qemu (-snapshot) incorrectly handles temporary
files used to store the current state, making it vulnerable to
symlink attacks (including arbitrary file overwriting and guest
information disclosure) due to a race condition.
CVE-2012-3515:
Qemu does not properly handle VT100 escape sequences when emulating
certain devices with a virtual console backend. An attacker within a
guest with access to the vulnerable virtual console could overwrite
memory of Qemu and escalate privileges to that of the qemu process.
For the stable distribution (squeeze), these problems have been fixed in
version 0.12.5+dfsg-5+squeeze9.
For the testing distribution (wheezy), and the unstable distribution
(sid), these problems will been fixed soon.
Recommendations:
We recommend that you upgrade your qemu-kvm Linux Distribution Packages.
Summary:
The remote host is missing an update to qemu-kvm
announced via advisory DSA 2542-1.

What's vulnerability management?
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".
