Race condition in the MutationObserver implementation in Blink, as used in Google Chrome before 47.0.2526.80, allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact by leveraging unanticipated object deletion.

kernel: net: inet frag code race condition leading to user-after-free

Race condition in the inet_frag_intern function in net/ipv4/inet_fragment.c in the Linux kernel through 3.13.6 allows remote attackers to cause a denial of service (use-after-free error) or possibly have unspecified other impact via a large series of fragmented ICMP Echo Request packets to a system with a heavy CPU load.

Race condition in the kernel in Microsoft Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, and Windows 10 Gold and 1511 allows local users to bypass the Low Integrity protection mechanism and write to files by leveraging unspecified object-manager features, aka "Windows File System Security Feature Bypass."

kernel: Race condition in packet_set_ring leads to use after free

Race condition in net/packet/af_packet.c in the Linux kernel through 4.8.12 allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging the CAP_NET_RAW capability to change a socket version, related to the packet_set_ring and packet_setsockopt functions.

Mozilla: Read of uninitialized memory in Web Audio (MFSA 2015-05)

The mozilla::dom::AudioParamTimeline::AudioNodeInputValue function in the Web Audio API implementation in Mozilla Firefox before 35.0 and SeaMonkey before 2.32 does not properly restrict timeline operations, which allows remote attackers to cause a denial of service (uninitialized-memory read and application crash) via crafted API calls.

Kernel: ALSA: control: protect user controls against races & memory disclosure

Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allows local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.

postgresql: CREATE INDEX race condition possibly leading to privilege escalation

Race condition in the (1) CREATE INDEX and (2) unspecified ALTER TABLE commands in PostgreSQL before 8.4.20, 9.0.x before 9.0.16, 9.1.x before 9.1.12, 9.2.x before 9.2.7, and 9.3.x before 9.3.3 allows remote authenticated users to create an unauthorized index or read portions of unauthorized tables by creating or deleting a table with the same name during the timing window.

openssl: Crash in ssleay_rand_bytes due to locking regression

Race condition in a certain Red Hat patch to the PRNG lock implementation in the ssleay_rand_bytes function in OpenSSL, as distributed in openssl-1.0.1e-25.el7 in Red Hat Enterprise Linux (RHEL) 7 and other products, allows remote attackers to cause a denial of service (application crash) by establishing many TLS sessions to a multithreaded server, leading to use of a negative value for a certain length field.

spice: memory corruption in worker_update_monitors_config()

Race condition in the worker_update_monitors_config function in SPICE 0.12.4 allows a remote authenticated guest user to cause a denial of service (heap-based memory corruption and QEMU-KVM crash) or possibly execute arbitrary code on the host via unspecified vectors.

kernel: multiple race conditions in aufs

Multiple race conditions in the Advanced Union Filesystem (aufs) aufs3-mmap.patch and aufs4-mmap.patch patches for the Linux kernel 3.x and 4.x allow local users to cause a denial of service (use-after-free and BUG) or possibly gain privileges via a (1) madvise or (2) msync system call, related to mm/madvise.c and mm/msync.c.

xen: Race between domain destruction and memory allocation decrease on ARM

Race condition in the relinquish_memory function in arch/arm/domain.c in Xen 4.6.x and earlier allows local domains with partial management control to cause a denial of service (host crash) via vectors involving the destruction of a domain and using XENMEM_decrease_reservation to reduce the memory of the domain.

Race condition in the administration-panel web service in IBM System Networking Switch Center (SNSC) before 7.3.1.5 and Lenovo Switch Center before 8.1.2.0 allows remote attackers to obtain privileged-account access, and consequently provide FileReader.jsp input containing directory traversal sequences to read arbitrary text files, via a request to port 40080 or 40443.

kernel: pty layer race condition on tty ldisc shutdown.

Race condition in the ldsem_cmpxchg function in drivers/tty/tty_ldsem.c in the Linux kernel before 3.13-rc4-next-20131218 allows local users to cause a denial of service (ldsem_down_read and ldsem_down_write deadlock) by establishing a new tty thread during shutdown of a previous tty thread.

Race condition in the IPv6-to-IPv4 functionality in Cisco IOS 15.3S in the Performance Routing Engine (PRE) module on UBR devices allows remote attackers to cause a denial of service (NULL pointer free and module crash) by triggering intermittent connectivity with many IPv6 CPE devices, aka Bug ID CSCug47366.

Race condition in the MoveFileEx call hook feature in Adobe Reader and Acrobat 11.x before 11.0.09 on Windows allows attackers to bypass a sandbox protection mechanism, and consequently write to files in arbitrary locations, via an NTFS junction attack, a similar issue to CVE-2014-0568.
