CVE-2014-5077

Status Candidate

Overview

The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction.

Red Hat Security Advisory 2014-1872-01
Posted Nov 18, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-1872-01 - 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. This update fixes several race conditions between PCI error recovery callbacks and potential calls of the ifup and ifdown commands in the tg3 driver. When triggered, these race conditions could cause a kernel crash.

Red Hat Security Advisory 2014-1763-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's futex subsystem handled reference counting when requeuing futexes during futex_wait(). A local, unprivileged user could use this flaw to zero out the reference counter of an inode or an mm struct that backs up the memory area of the futex, which could lead to a use-after-free flaw, resulting in a system crash or, potentially, privilege escalation. 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.

Red Hat Security Advisory 2014-1724-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: 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 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.

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.
