Debian Security Advisory DSA-2666-1 [email protected]

Package : xen
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2013-1918 CVE-2013-1952 CVE-2013-1964
Multiple vulnerabilities have been discovered in the Xen hypervisor. 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
version 4.1.4-3+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.
