648658: CVE-2010-4073 kernel: ipc/compat*.c: reading uninitialized stack memory

The MITRE CVE dictionary describes this issue as:

The ipc subsystem in the Linux kernel before 2.6.37-rc1 does not initialize certain structures, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to the (1) compat_sys_semctl, (2) compat_sys_msgctl, and (3) compat_sys_shmctl functions in ipc/compat.c; and the (4) compat_sys_mq_open and (5) compat_sys_mq_getsetattr functions in ipc/compat_mq.c.

Statement

This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3 as it did not include IPC compat functionality.
