Not Vulnerable:	Linux kernel 2.6.20

Linux Kernel BINFMT_ELF PT_INTERP Local Information Disclosure Vulnerability

The Linux kernel is prone to a vulnerability in the Linux ELF binary loader. Exploiting this issue can allow local attackers to gain access to privileged information.

An attacker may be able to obtain sensitive data that can potentially be used to gain elevated privileges.

This issue is a variant of the vulnerability assigned CVE candidate ID CAN-2004-1073, which is documented in BID 11646.

Linux Kernel versions in the 2.6.0 branch prior to 2.6.20 are vulnerable; versions in the 2.4.0 branch may also be affected.
