Debian: DSA-2666-1 Critical: Xen Denial of Service Risks

Multiple vulnerabilities have been discovered in the Xen hypervisor. The Common Vulnerabilities and Exposures project identifies the following problems: . -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2666-1 This email address is being protected from spambots.

The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2013-1918 (XSA 45) Several long latency operations are not preemptible Some page table manipulation operations for PV guests were not made preemptible, allowing a malicious or buggy PV guest kernel to mount a denial of service attack affecting the whole system. CVE-2013-1952 (XSA 49) VT-d interrupt remapping source validation flaw for bridges Due to missing source validation on interrupt remapping table entries for MSI interrupts set up by bridge devices, a malicious domain with access to such a device, can mount a denial of service attack affecting the whole system. CVE-2013-1964 (XSA 50) grant table hypercall acquire/release imbalance When releasing a particular, non-transitive grant after doing a grant copy operation Xen incorrectly releases an unrelated grant reference, leading possibly to a crash of the host system. Furthermore information leakage or privilege escalation cannot be ruled out. For the oldstable distribution (squeeze), these problems have been fixed in version 4.0.1-5.11. For the stable distribution (wheezy), these problems have been fixed in version4.1.4-3+deb7u1. For the testing distribution (jessie), these problems have been fixed in version 4.1.4-4. For the unstable distribution (sid), these problems have been fixed in version 4.1.4-4. Note that for the stable (wheezy), testing and unstable distribution, CVE-2013-1964 (XSA 50) was already fixed in version 4.1.4-3. We recommend that you upgrade your xen packages.
