http://www.debian.org/security/2010/dsa-2010Several local vulnerabilities have been discovered in kvm, a full virtualization system. The Common Vulnerabilities and Exposures project identifies the following problems:
CVE-2010-0298 & CVE-2010-0306
Gleb Natapov discovered issues in the KVM subsystem where missing permission checks (CPL/IOPL) permit a user in a guest system to denial of service a guest (system crash) or gain escalated privileges with the guest.
CVE-2010-0309
Marcelo Tosatti fixed an issue in the PIT emulation code in the KVM subsystem that allows privileged users in a guest domain to cause a denial of service (crash) of the host system.
CVE-2010-0419
Paolo Bonzini found a bug in KVM that can be used to bypass proper permission checking while loading segment selectors. This potentially allows privileged guest users to execute privileged instructions on the host system.
http://www.debian.org/security/2010/dsa-2011DSA-2011-1 dpkg -- path traversal
Date Reported:
10 Mar 2010
Affected Packages:
dpkg
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2010-0396.
More information:
William Grant discovered that the dpkg-source component of dpkg, the low-level infrastructure for handling the installation and removal of Debian software packages, is vulnerable to path traversal attacks. A specially crafted Debian source package can lead to file modification outside of the destination directory when extracting the package content.
For the stable distribution (lenny), this problem has been fixed in version 1.14.29.
For the testing (squeeze) and unstable (sid) distribution this problem will be fixed soon.
We recommend that you upgrade your dpkg packages.
Petite tête !pong en voulant redémarrer le serveur xorg j'ai rebooté tout le serveur
mais en une fraction de secondes j'ai réalisé que ça allait rebooterCtrl+Alt+Backspace sequence. That sequence is normally used to terminate the Xorg server. When this option is enabled, that key sequence has no special meaning and is passed to clients. Default: off.
