The manipulation with an unknown input leads to a local privilege escalation vulnerability. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
** DISPUTED ** The source code tar archive of the Linux kernel 2.6.16, 2.6.17.11, and possibly other versions specifies weak permissions (0666 and 0777) for certain files and directories, which might allow local users to insert Trojan horse source code that would be used during the next kernel compilation.
