Alpine: multiple xen packages: security update to 4.1.0-r2 (deprecated)

critical Tenable Cloud Security Plugin ID 401345

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Multiple integer overflows in tools/libxc/xc_dom_bzimageloader.c in Xen 3.2, 3.3, 4.0, and 4.1 allow local
users to cause a denial of service and possibly execute arbitrary code via a crafted paravirtualised guest
kernel image that triggers (1) a buffer overflow during a decompression loop or (2) an out-of-bounds read
in the loader involving unspecified length fields. (CVE-2011-1583)

- Xen 4.1 before 4.1.1 and 4.0 before 4.0.2, when using PCI passthrough on Intel VT-d chipsets that do not
have interrupt remapping, allows guest OS users to gain host OS privileges by "using DMA to generate MSI
interrupts by writing to the interrupt injection registers." (CVE-2011-1898)
