Christey" <coley@...us.mitre.org> To: OSS Security List <oss-security@...ts.openwall.com> Subject: Re: CVE Request: XEN local denial of service More specific information on Xen's affected versions would be appreciated. I made a guess based on the version that was released a few days after the patch. - Steve ====================================================== Name: CVE-2009-1758 Status: Candidate URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1758 Reference: MLIST:[Xen-devel] 20090513 [PATCH] linux/i386: hypervisor_callback adjustments Reference: URL:http://lists.xensource.com/archives/html/xen-devel/2009-05/msg00561.html Reference: MLIST:[oss-security] 20090514 CVE Request: XEN local denial of service Reference: URL:http://www.openwall.com/lists/oss-security/2009/05/14/2 The hypervisor_callback function in Xen, possibly before 3.4.0, as applied to the Linux kernel 2.6.30-rc4, 2.6.18, and probably other versions allows guest user applications to cause a denial of service (kernel oops) of the guest OS by triggering a segmentation fault in "certain address ranges."
