kernel: Race condition vulnerability in execve argv arguments

Race condition in the audit_log_single_execve_arg function in kernel/auditsc.c in the Linux kernel through 4.7 allows local users to bypass intended character-set restrictions or disrupt system-call auditing by changing a certain string, aka a "double fetch" vulnerability.

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.

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: 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.

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.

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.

Race condition in the client in IBM Tivoli Storage Manager (TSM) 5.4.0.0 through 5.4.3.6, 5.5.0.0 through 5.5.4.3, 6.1.0.0 through 6.1.5.6, 6.2 before 6.2.5.4, 6.3 before 6.3.2.3, 6.4 before 6.4.2.1, and 7.1 before 7.1.1 on UNIX and Linux allows local users to obtain root privileges via unspecified vectors.

llvm: insecure temporary file handling in clang's scan-build utility

The GetHTMLRunDir function in the scan-build utility in Clang 3.5 and earlier allows local users to obtain sensitive information or overwrite arbitrary files via a symlink attack on temporary directories with predictable names.

Race condition in the setreuid system-call implementation in the kernel in Apple iOS before 8.3, Apple OS X before 10.10.3, and Apple TV before 7.2 allows attackers to cause a denial of service via a crafted app.

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.

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.

kernel: sound: GPF in snd_timer_user_params

sound/core/timer.c in the Linux kernel before 4.4.1 uses an incorrect type of mutex, which allows local users to cause a denial of service (race condition, use-after-free, and system crash) via a crafted ioctl call.

kernel: Unauthorized access to IPC objects with SysV shm

Race condition in the IPC object implementation in the Linux kernel through 4.2.3 allows local users to gain privileges by triggering an ipc_addid call that leads to uid and gid comparisons against uninitialized data, related to msg.c, shm.c, and util.c.

ppc64-diag: multiple temporary file races

ppc64-diag 2.6.1 uses 0775 permissions for /tmp/diagSEsnap and does not properly restrict permissions for /tmp/diagSEsnap/snapH.tar.gz, which allows local users to obtain sensitive information by reading files in this archive, as demonstrated by /var/log/messages and /etc/yaboot.conf.

ppc64-diag: multiple temporary file races

ppc64-diag 2.6.1 allows local users to overwrite arbitrary files via a symlink attack related to (1) rtas_errd/diag_support.c and /tmp/get_dt_files, (2) scripts/ppc64_diag_mkrsrc and /tmp/diagSEsnap/snapH.tar.gz, or (3) lpd/test/lpd_ela_test.sh and /var/tmp/ras.

Kernel: missing check during hugepage migration

The Linux kernel through 3.14.5 does not properly consider the presence of hugetlb entries, which allows local users to cause a denial of service (memory corruption or system crash) by accessing certain memory locations, as demonstrated by triggering a race condition via numa_maps read operations during hugepage migration, related to fs/proc/task_mmu.c and mm/mempolicy.c.

Bluetooth in Android 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-07-01 allows local users to gain privileges by establishing a pairing that remains present during a session of the primary user, aka internal bug 27410683.

rubygem-kafo: temporary file creation vulnerability when creating /tmp/default_values.yaml

Kafo before 0.3.17 and 0.4.x before 0.5.2, as used by Foreman, uses world-readable permissions for default_values.yaml, which allows local users to obtain passwords and other sensitive information by reading the file.

rpm: race condition during the installation process

Race condition in RPM 4.11.1 and earlier allows remote attackers to execute arbitrary code via a crafted RPM file whose installation extracts the contents to temporary files before validating the signature, as demonstrated by installing a file in the /etc/cron.d directory.
