MiracleLinux 3 : xen-3.0.3-64.3.1AXS3 (AXSA:2008-443:02)

high Nessus Plugin ID 284476

Synopsis

The remote MiracleLinux host is missing one or more security updates.

Description

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2008-443:02 advisory.

 This package contains the Xen tools and management daemons needed to run virtual machines.
 Information on how to use Xen can be found at the Xen project pages.
 The Xen system also requires the Xen hypervisor and domain-0 kernel, which can be found in the kernel-xen* package.
 Virtualization can be used to run multiple operating systems on one physical system, for purposes of hardware consolidation, hardware abstraction, or to test untrusted applications in a sandboxed environment.
 Bugs fixed:
 CVE-2007-4993 pygrub (tools/pygrub/src/GrubConf.py) in Xen 3.0.3, when booting a guest domain, allows local users with elevated privileges in the guest domain to execute arbitrary commands in domain 0 via a crafted grub.conf file whose contents are used in exec statements.
 CVE-2007-1321 Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to trigger a heap-based buffer overflow via certain register values that bypass sanity checks, aka QEMU NE2000 receive integer signedness error. NOTE: this identifier was inadvertently used by some sources to cover multiple issues that were labeled NE2000 network driver and the socket code, but separate identifiers have been created for the individual vulnerabilities since there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730.
 CVE-2007-3919 (1) xenbaked and (2) xenmon.py in Xen 3.1 and earlier allow local users to truncate arbitrary files via a symlink attack on /tmp/xenq-shm.
 CVE-2008-0928 Qemu 0.9.1 and earlier does not perform range checks for block device read or write requests, which allows guest host users with root privileges to access arbitrary memory and escape the virtual machine.
 CVE-2007-5730 Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to execute arbitrary code via crafted data in the net socket listen option, aka QEMU net socket heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of NE2000 network driver and the socket code, but this is the correct identifier for the individual net socket listen vulnerability.
 CVE-2008-2004 The drive_init function in QEMU 0.9.1 determines the format of a raw disk image based on the header, which allows local guest users to read arbitrary files on the host by modifying the header to identify a different format, which is used when the guest is restarted.
 CVE-2008-1945 QEMU 0.9.0 does not properly handle changes to removable media, which allows guest OS users to read arbitrary files on the host OS by using the diskformat: parameter in the -usbdevice option to modify the disk-image header to identify a different format, a related issue to CVE-2008-2004.
 CVE-2008-1952 The backend for XenSource Xen Para Virtualized Frame Buffer (PVFB) in Xen ioemu does not properly restrict the frame buffer size, which allows attackers to cause a denial of service (crash) by mapping an arbitrary amount of guest memory.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected xen, xen-devel and / or xen-libs packages.
