CVE-2013-2148

Status Candidate

Overview

The fill_event_metadata function in fs/notify/fanotify/fanotify_user.c in the Linux kernel through 3.9.4 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory via a read operation on the fanotify descriptor.

Red Hat Security Advisory 2013-1264-01
Posted Sep 16, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-1264-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A heap-based buffer overflow flaw was found in the Linux kernel's iSCSI target subsystem. A remote attacker could use a specially-crafted iSCSI request to cause a denial of service on a system or, potentially, escalate their privileges on that system. A flaw was found in the Linux kernel's Performance Events implementation. On systems with certain Intel processors, a local, unprivileged user could use this flaw to cause a denial of service by leveraging the perf subsystem to write into the reserved bits of the OFFCORE_RSP_0 and OFFCORE_RSP_1 model-specific registers.

Mandriva Linux Security Advisory 2013-194
Posted Jul 11, 2013
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2013-194 - Multiple vulnerabilities has been found and corrected in the Linux kernel. net/ceph/auth_none.c in the Linux kernel through 3.10 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an auth_reply message that triggers an attempted build_request operation. The HP Smart Array controller disk-array driver and Compaq SMART2 controller disk-array driver in the Linux kernel through 3.9.4 do not initialize certain data structures, which allows local users to obtain sensitive information from kernel memory via a crafted IDAGETPCIINFO command for a /dev/ida device, related to the ida_locked_ioctl function in drivers/block/cpqarray.c or a crafted CCISS_PASSTHRU32 command for a /dev/cciss device, related to the cciss_ioctl32_passthru function in drivers/block/cciss.c. Various other issues have also been addressed. The updated packages provides a solution for these security issues.
