An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. macOS before 10.12.5 is affected. tvOS before 10.2.1 is affected. watchOS before 3.2.2 is affected. The issue involves the "Kernel" component. A race condition allows attackers to execute arbitrary code in a privileged context via a crafted app.

open-vm-tools: /tmp race conditions in the libDeployPkg component

VMware Tools prior to 10.0.9 contains multiple file system races in libDeployPkg, related to the use of hard-coded paths under /tmp. Successful exploitation of this issue may result in a local privilege escalation. CVSS:3.0/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H

abrt: Various race-conditions and symlink issues found in abrt

Automatic Bug Reporting Tool (ABRT) allows local users to read, change the ownership of, or have other unspecified impact on arbitrary files via a symlink attack on (1) /var/tmp/abrt/*/maps, (2) /tmp/jvm-*/hs_error.log, (3) /proc/*/exe, (4) /etc/os-release in a chroot, or (5) an unspecified root directory related to librpm.

In all Android releases from CAF using the Linux kernel, a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability exists in Secure Display.

In the Embedded File System in all Android releases from CAF using the Linux kernel, a Time-of-Check Time-of-Use Race Condition vulnerability could potentially exist.

kernel: Race condition in the ip4_datagram_release_cb function

Race condition in the ip4_datagram_release_cb function in net/ipv4/datagram.c in the Linux kernel before 3.15.2 allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging incorrect expectations about locking during multithreaded access to internal data structures for IPv4 UDP sockets.

The setpermissions function in the auto-updater in Arq before 5.9.7 for Mac allows local users to gain root privileges via a symlink attack on the updater binary itself.

Race condition in Blizzard Overwatch 1.15.0.2 allows remote authenticated users to cause a denial of service (season bans and SR losses for other users) by leaving a competitive match at a specific time during the initial loading of that match.

libsndfile: Divide-by-zero in the double64_init() function

In libsndfile 1.0.28, a divide-by-zero error exists in the function double64_init() in double64.c, which may lead to DoS when playing a crafted audio file.

CDirVector::GetTable in dirfunc.hxx in libfpx 1.3.1_p6 allows remote attackers to cause a denial of service (divide-by-zero error) via a crafted fpx image.

sox: Devide by zero in wavwritehdr function in wav.c

The wavwritehdr function in wav.c in Sound eXchange (SoX) 14.4.2 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted snd file, during conversion to a wav file.

yadm (yet another dotfile manager) 1.10.0 has a race condition (related to the behavior of git commands in setting permissions for new files and directories), which potentially allows access to SSH and PGP keys.

sox: Divide by zero in startread function in wav.c

The startread function in wav.c in Sound eXchange (SoX) 14.4.2 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted wav file.

kernel: Handling of might_cancel queueing is not properly pretected against race

Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing.

kernel: pmd can become dirty without going through a COW cycle

The Linux Kernel versions 2.6.38 through 4.14 have a problematic use of pmd_mkdirty() in the touch_pmd() function inside the THP implementation. touch_pmd() can be reached by get_user_pages(). In such case, the pmd will become dirty. This scenario breaks the new can_follow_write_pmd()'s logic - pmd can become dirty without going through a COW cycle. This bug is not as severe as the original "Dirty cow" because an ext4 file (or any other regular file) cannot be mapped using THP. Nevertheless, it does allow us to overwrite read-only huge pages. For example, the zero huge page and sealed shmem files can be overwritten (since their mapping can be populated using THP). Note that after the first write page-fault to the zero page, it will be replaced with a new fresh (and zeroed) thp.

The Windows NetBT Session Services component on Microsoft Windows Server 2008 R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, Windows 10 Gold, 1511, 1607, and 1703, and Windows Server 2016 allows a remote code execution vulnerability when it fails to maintain certain sequencing requirements, aka "NetBIOS Remote Code Execution Vulnerability".

xen: qemu incautious about shared ring processing (XSA-197)

Race condition in QEMU in Xen allows local x86 HVM guest OS administrators to gain privileges by changing certain data on shared rings, aka a "double fetch" vulnerability.
