|Bugzilla:||648656: CVE-2010-4072 kernel: ipc/shm.c: reading uninitialized stack memory|
The MITRE CVE dictionary describes this issue as:
The copy_shmid_to_user function in ipc/shm.c in the Linux kernel before 2.6.37-rc1 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to the shmctl system call and the "old shm interface."
This issue is not planned to be fixed in Red Hat Enterprise Linux 3, due to this product being in Extended Life Cycle Phase of its maintenance life-cycle, where only qualified security errata of critical impact are addressed.
