CVE-2013-4483

Status Candidate

Overview

The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a reference count, which allows local users to cause a denial of service (memory consumption or system crash) via a crafted application.

Red Hat Security Advisory 2015-0284-03
Posted Mar 3, 2015
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2015-0284-03 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. A flaw was found in the way the Linux kernel's SCTP implementation validated INIT chunks when performing Address Configuration Change. A remote attacker could use this flaw to crash the system by sending a specially crafted SCTP packet to trigger a NULL pointer dereference on the system.

Red Hat Security Advisory 2014-1392-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. An integer overflow flaw was found in the way the Linux kernel's Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file could possibly use this flaw to escalate their privileges on the system.

Red Hat Security Advisory 2014-0285-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A buffer overflow flaw was found in the way the qeth_snmp_command() function in the Linux kernel's QETH network device driver implementation handled SNMP IOCTL requests with an out-of-bounds length. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. A flaw was found in the way the ipc_rcu_putref() function in the Linux kernel's IPC implementation handled reference counter decrementing. A local, unprivileged user could use this flaw to trigger an Out of Memory condition and, potentially, crash the system.

Mandriva Linux Security Advisory 2013-265 - Multiple vulnerabilities has been found and corrected in the Linux kernel. The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a reference count, which allows local users to cause a denial of service via a crafted application. The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service via a small value in the IHL field of a packet with IPIP encapsulation. Various other issues have also been addressed.
