Description:

   - CVE-2015-7613: A race condition in the IPC object implementation in the
     Linux kernel allowed local users to gain privileges by triggering an
     ipc_addid call that leads to uid and gid comparisons against
     uninitialized data, related to msg.c, shm.c, and util.c. (bsc#948701
     bsc#948536)
   - CVE-2015-5707: Integer overflow in the sg_start_req function in
     drivers/scsi/sg.c in the Linux kernel allowed local users to cause a
     denial of service or possibly have unspecified other impact via a large
     iov_count value in a write request. (bsc#940342 bsc#940338)
