Vulnerability CVE-2008-3247 - CERT Civis.Net

Vulnerability Name:

CVE-2008-3247 (CCN-43979)

Assigned:

2008-07-22

Published:

2008-07-22

Updated:

2017-08-08

Summary:

The LDT implementation in the Linux kernel 2.6.25.x before 2.6.25.11 on x86_64 platforms uses an incorrect size for ldt_desc, which allows local users to cause a denial of service (system crash) or possibly gain privileges via unspecified vectors.
