CVE-2010-4083

Priority
Description
The copy_semid_to_user function in ipc/sem.c in the Linux kernel before
2.6.36 does not initialize a certain structure, which allows local users to
obtain potentially sensitive information from kernel stack memory via a (1)
IPC_INFO, (2) SEM_INFO, (3) IPC_STAT, or (4) SEM_STAT command in a semctl
system call.
Ubuntu-Description
Dan Rosenberg discovered that the semctl syscall did not correctly clear
kernel memory. A local attacker could exploit this to read kernel stack
memory, leading to a loss of privacy.
