dbus: denial of service in dbus systemd activation

D-Bus 1.4.x through 1.6.x before 1.6.30, 1.8.x before 1.8.16, and 1.9.x before 1.9.10 does not validate the source of ActivationFailure signals, which allows local users to cause a denial of service (activation failure error returned) by leveraging a race condition involving sending an ActivationFailure signal before systemd responds.

chromium-browser: type confusion in Blink

The ImageInputType::ensurePrimaryContent function in WebKit/Source/core/html/forms/ImageInputType.cpp in Blink, as used in Google Chrome before 49.0.2623.87, does not properly maintain the user agent shadow DOM, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that leverage "type confusion."

libsndfile: division by zero leading to denial of service in psf_fwrite()

The psf_fwrite function in file_io.c in libsndfile allows attackers to cause a denial of service (divide-by-zero error and application crash) via unspecified vectors related to the headindex variable.

Kernel: fs: btrfs: non-atomic xattr replace operation

The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.

kernel: race condition in the TLB flush logic

Race condition in arch/x86/mm/tlb.c in the Linux kernel before 4.4.1 allows local users to gain privileges by triggering access to a paging structure by a different CPU.

vorbis-tools: division by zero on crafted WAV file

oggenc in vorbis-tools 1.4.0 allows remote attackers to cause a denial of service (divide-by-zero error and crash) via a WAV file with the number of channels set to zero.

kernel: use-after-free during key garbage collection

Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key.

bind: race condition when handling socket errors can lead to an assertion failure in resolver.c

Race condition in resolver.c in named in ISC BIND 9.9.8 before 9.9.8-P2 and 9.10.3 before 9.10.3-P2 allows remote attackers to cause a denial of service (INSIST assertion failure and daemon exit) via unspecified vectors.

Race condition in Lenovo System Update (formerly ThinkVantage System Update) before 5.06.0034 uses world-writable permissions for the update files directory, which allows local users to gain privileges by writing to an update file after the signature is validated.

Race condition in Adobe Flash Player before 13.0.0.289 and 14.x through 17.x before 17.0.0.188 on Windows and OS X and before 11.2.202.460 on Linux, Adobe AIR before 17.0.0.172, Adobe AIR SDK before 17.0.0.172, and Adobe AIR SDK & Compiler before 17.0.0.172 allows attackers to bypass the Internet Explorer Protected Mode protection mechanism via unspecified vectors.

Multiple race conditions in IBM WebSphere Application Server (WAS) 8.5 Liberty Profile before 8.5.5.5 allow remote authenticated users to gain privileges by leveraging thread conflicts that result in Java code execution outside the context of the configured EJB Run-as user.

kernel: kvm: PIT timer race condition

Race condition in the __kvm_migrate_pit_timer function in arch/x86/kvm/i8254.c in the KVM subsystem in the Linux kernel through 3.17.2 allows guest OS users to cause a denial of service (host OS crash) by leveraging incorrect PIT emulation.

python: os.makedirs(exist_ok=True) is not thread-safe in Python 3.x

Race condition in the _get_masked_mode function in Lib/os.py in Python 3.2 through 3.5, when exist_ok is set to true and multiple threads are used, might allow local users to bypass intended file permissions by leveraging a separate application vulnerability before the umask has been set to the expected value.

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.

Qemu: display: cirrus_vga: a divide by zero in cirrus_do_copy

Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to a divide by zero issue. It could occur while copying VGA data when cirrus graphics mode was set to be VGA. A privileged user inside guest could use this flaw to crash the Qemu process instance on the host, resulting in DoS.

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.

chromium-browser: buffer overflow via race condition in GPU

Race condition in gpu/command_buffer/service/gles2_cmd_decoder.cc in Google Chrome before 41.0.2272.118 allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact by manipulating OpenGL ES commands.

Race condition in pxz 4.999.99 Beta 3 uses weak file permissions for the output file when compressing a file before changing the permission to match the original file, which allows local users to bypass the intended access restrictions.

Unity before 7.2.3 and 7.3.x before 7.3.1, as used in Ubuntu, does not properly take focus of the keyboard when switching to the lock screen, which allows physically proximate attackers to bypass the lock screen by (1) leveraging a machine that had text selected when locking or (2) resuming from a suspension.

Race condition in iMessage in Apple iOS before 8 allows attackers to obtain sensitive information by leveraging the presence of an attachment after the deletion of its parent (1) iMessage or (2) MMS.
