Description

This security bulletin contains information about 1 vulnerability.


1) Improper input validation (CVE-ID: CVE-2010-0730)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The MMIO instruction decoder in the Xen hypervisor in the Linux kernel 2.6.18 in Red Hat Enterprise Linux (RHEL) 5 allows guest OS users to cause a denial of service (32-bit guest OS crash) via vectors that trigger an unspecified instruction emulation. Per: http://secunia.com/advisories/39649 'Successful exploitation requires a 32bit system and access to an MMIO region.'
