CVSS v3.1 |
| 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. |
| authd sets weak permissions for /etc/ident.key, which allows local users to obtain the key by leveraging a race condition between the creation of the key, and the chmod to protect it. |
| In all Qualcomm products with Android releases from CAF using the Linux kernel, a race condition can allow access to already freed memory while querying event status via DCI. |
| aRts 1.5.10 and kdelibs3 3.5.10 and earlier do not properly create temporary directories, which allows local users to hijack the IPC by pre-creating the temporary directory. |
| In Android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, due to a race condition in the GLink kernel driver, a Use After Free condition can potentially occur. |
| 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. |
| In HashiCorp Vagrant VMware Fusion plugin (aka vagrant-vmware-fusion) 5.0.0, a local attacker or malware can silently subvert the plugin update process in order to escalate to root privileges. |
| In all Qualcomm products with Android releases from CAF using the Linux kernel, a race condition exists in a driver potentially leading to a use-after-free condition. |
| In GNU Libextractor 1.4, there is a Divide-By-Zero in EXTRACTOR_wav_extract_method in wav_extractor.c via a zero sample rate. |
| Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel before 4.8.14 allows local users to gain privileges or cause a denial of service (use-after-free) by making multiple bind system calls without properly ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c. |
| In FreeBSD through 11.1, the smb_strdupin function in sys/netsmb/smb_subr.c has a race condition with a resultant out-of-bounds read, because it can cause t2p->t_name strings to lack a final '\0' character. |
| The Microsoft Device Guard on Microsoft Windows 10 Gold, 1511, 1607, and 1703, and Windows Server 2016 allows a security feature bypass by the way it handles Windows PowerShell sessions, aka "Microsoft Windows Security Feature Bypass". |
| A domain cleanup issue was discovered in the C xenstore daemon (aka cxenstored) in Xen through 4.9.x. When shutting down a VM with a stubdomain, a race in cxenstored may cause a double-free. The xenstored daemon may crash, resulting in a DoS of any parts of the system relying on it (including domain creation / destruction, ballooning, device changes, etc.). |
| The jpc_dec_process_siz function in libjasper/jpc/jpc_dec.c in JasPer before 1.900.4 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted YRsiz value in a BMP image to the imginfo command. |
| The jpc_dec_process_siz function in libjasper/jpc/jpc_dec.c in JasPer before 1.900.4 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted XRsiz value in a BMP image to the imginfo command. |
| In all Android releases from CAF using the Linux kernel, a race condition exists in a QTEE driver potentially leading to an arbitrary memory write. |
| In all Qualcomm products with Android releases from CAF using the Linux kernel, there is a TOCTOU race condition in Secure UI. |
| The JPEGSetupEncode function in tiff_jpeg.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted image. |
| Google Chrome prior to 57.0.2987.98 for Windows and Mac had a race condition, which could cause Chrome to display incorrect certificate information for a site. |
| 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. |
