Improper Validation of Array Index

Array index error in the scanstring function in the _json module in Python 2.7 through 3.5 and simplejson before 2.6.1 allows context-dependent attackers to read arbitrary process memory via a negative index value in the idx argument to the raw_decode function.Show less

The NFSv4 server in the Linux kernel before 4.11.3 does not properly validate the layout type when processing the NFSv4 pNFS GETDEVICEINFO or LAYOUTGET operand in a UDP packet from a remote attacker. This type value is uninitialized upon encountering certain error conditions. This value is used as an array index for dereferencing, which leads to an OOPS and eventually a DoS of knfsd and a soft-lockup of the whole system.Show less

All versions of the NVIDIA Windows GPU Display Driver contain a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape where a value passed from a user to the driver is not correctly validated and used as the index to an array, which may lead to denial of service or potential escalation of privileges.Show less

All versions of the NVIDIA Windows GPU Display Driver contain a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape where user provided input used as an array size is not correctly validated allows out of bound access in kernel memory and may lead to denial of service or potential escalation of privilegesShow less

An issue (known as XSA-212) was discovered in Xen, with fixes available for 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x. The earlier XSA-29 fix introduced an insufficient check on XENMEM_exchange input, allowing the caller to drive hypervisor memory accesses outside of the guest provided input/output arrays.Show less

An exploitable out-of-bounds indexing vulnerability exists within the RW fabric message particle type of Aerospike Database Server 3.10.0.3. A specially crafted packet can cause the server to fetch a function table outside the bounds of an array resulting in remote code execution. An attacker can simply connect to the port to trigger this vulnerability.Show less

All versions of NVIDIA Windows GPU Display Driver contain a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape where a value passed from a user to the driver is used without validation as the index to an array, leading to denial of service or potential escalation of privileges.Show less

The vmsvga_fifo_run function in hw/display/vmware_vga.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via vectors related to cursor.mask[] and cursor.image[] array sizes when processing a DEFINE_CURSOR svga command.Show less

Array index error in win32k.sys in the kernel-mode drivers in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allows remote attackers to cause a denial of service (reboot) via a crafted TrueType font, aka "Denial of Service in Windows Kernel Mode Driver Vulnerability."Show less

Array index error in the asihpi_hpi_ioctl function in sound/pci/asihpi/hpioctl.c in the AudioScience HPI driver in the Linux kernel before 2.6.38.1 might allow local users to cause a denial of service (memory corruption) or possibly gain privileges via a crafted adapter index value that triggers access to an invalid kernel pointer.Show less

Array index error in the t42_parse_sfnts function in type42/t42parse.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via negative size values for certain strings in FontType42 font files, leading to a heap-based buffer overflow.Show less

Array index error in the gdth_read_event function in drivers/scsi/gdth.c in the Linux kernel before 2.6.32-rc8 allows local users to cause a denial of service or possibly gain privileges via a negative event index in an IOCTL request.Show less
