Alpine: multiple xen packages: security update to 4.2.0-r6 (deprecated)
high Tenable Cloud Security Plugin ID 401327
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which
allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges
via unspecified vectors that overwrite memory in the hypervisor reserved range. (CVE-2012-5513)
- Xen 4.x, when downgrading the grant table version, does not properly remove the status page from the
tracking list when freeing the page, which allows local guest OS administrators to cause a denial of
service (hypervisor crash) via unspecified vectors. (CVE-2012-5510)
- Stack-based buffer overflow in the dirty video RAM tracking functionality in Xen 3.4 through 4.1 allows
local HVM guest OS administrators to cause a denial of service (crash) via a large bitmap image.
(CVE-2012-5511)
- The guest_physmap_mark_populate_on_demand function in Xen 4.2 and earlier does not properly unlock the
subject GFNs when checking if they are in use, which allows local guest HVM administrators to cause a
denial of service (hang) via unspecified vectors. (CVE-2012-5514)
