Bug#685221: unblock: xen/4.1.3-1
Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock
Please unblock xen/4.1.3-1. It updates the package to the release. By
doing this it fixes two security bugs, error handling in exceptional
conditions, missing access control and adds hardware support.
It also includes a build fix (removal of asmlinkage, which is a larger
fraction of the overall patch) for gcc 4.7 that was already fixed for
Debian in a different way.
xen (4.1.3-1) unstable; urgency=medium
* New upstream release: (closes: #683286)
- Don't leave the x86 emulation in a bad state. (closes: #683279)
CVE-2012-3432
- Only check for shared pages while any exist on teardown.
CVE-2012-3433
- Fix error handling for unexpected conditions.
- Update CPUID masking to latest Intel spec.
- Allow large ACPI ids.
- Fix IOMMU support for PCI-to-PCIe bridges.
- Disallow access to some sensitive IO-ports.
- Fix wrong address in IOTLB.
- Fix deadlock on CPUs without working cpufreq driver.
- Use uncached disk access in qemu.
- Fix buffer size on emulated e1000 device in qemu.
* Fixup broken and remove applied patches.
