CVE-2012-4544

Insufficient validation of kernel or ramdisk sizes in the Xen PV domain builder could result in denial of service.

CVE-2012-5511

Several HVM control operations performed insufficient validation of input, which could result in denial of service through resource exhaustion.

CVE-2012-5634

Incorrect interrupt handling when using VT-d hardware could result in denial of service.

CVE-2013-0153

Insufficient restriction of interrupt access could result in denial of service.

For the stable distribution (squeeze), these problems have been fixed in version 4.0.1-5.8.

For the testing distribution (wheezy), these problems have been fixed in version 4.1.4-2.

For the unstable distribution (sid), these problems have been fixed in version 4.1.4-2.

We recommend that you upgrade your xen packages.");
