======================================================
Name: CVE-2008-4410
Status: Candidate
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4410
Reference: MLIST:[oss-security] 20081003 CVE request: kernel: x86: Fix broken LDT access in VMI
Reference: URL:http://www.openwall.com/lists/oss-security/2008/10/03/3
Reference: CONFIRM:http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.26.y.git;a=commit;h=de59985e3a623d4d5d6207f1777398ca0606ab1c
The vmi_write_ldt_entry function in arch/x86/kernel/vmi_32.c in the
Virtual Machine Interface (VMI) in the Linux kernel 2.6.26.5 invokes
write_idt_entry where write_ldt_entry was intended, which allows local
users to cause a denial of service (persistent application failure)
via crafted function calls, related to the Java Runtime Environment
(JRE) experiencing improper LDT selector state, a different
vulnerability than CVE-2008-3247.
