CVE-2020-8940

CVE-2020-8940 describes an arbitrary memory read in Asylo up to version 0.6.0, where an attacker can cause a read via enc_untrusted_recvmsg using a attacker-controlled result parameter. The parameter size is unchecked, enabling reads beyond the intended buffer, potentially accessing memory locati...

CVE-2020-8937 Arbitrary enclave memory location write from untrusted environment

An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to encuntrustedcreatewaitqueue that uses a pointer queue that relies on UntrustedLocalMemcpy, which fails to validate where the pointer is located. This allows an attacker to write...

CVE-2020-8936 Arbitrary enclave memory overwrite vulnerability in ECall ecall_restore

An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to UntrustedCall. UntrustedCall failed to validate the buffer range within sgxparams and allowed the host to return a pointer that was an address within the enclave memory. This allowe...

CVE-2020-8935

An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allow an attacker to make an Ecallrestore function call to reallocate untrusted code and overwrite sections of the Enclave memory address. We recommend updating your library...

CVE-2020-13498

Pixar OpenUSD 20.05 is vulnerable to an out-of-bounds read related to index handling in the USD binary file format. The Talos report details three CVEs (TfToken, String, and SdfPath index reads) where missing bounds checks on internal token/path indices can allow reading beyond the allocated arra...

CVE-2020-13497

An exploitable vulnerability exists in the way Pixar OpenUSD 20.05 handles parses certain encoded types. A specially crafted malformed file can trigger an arbitrary out of bounds memory access in String Type Index. This vulnerability could be used to bypass mitigations and aid further exploitatio...

CVE-2020-28922

CVE-2020-28922 affects Devid Espenschied PC Analyser up to version 4.10, where the PCADRVX64.SYS kernel driver exposes IOCTLs that allow a low-privilege user to read and write arbitrary physical memory. This leads to potential arbitrary Ring-0 code execution and privilege escalation. The connecte...

Improper neutralization of null byte leads to read overrun

A user authorized to perform database queries may trigger a read overrun and access arbitrary memory by issuing specially crafted queries. This issue affects: MongoDB Inc. MongoDB Server v4.4 versions prior to 4.4.1; v4.2 versions prior to 4.2.9; v4.0 versions prior to 4.0.20; v3.6 versions prior...

CVE-2020-15481

An issue was discovered in PassMark BurnInTest v9.1 Build 1008, OSForensics v7.1 Build 1012, and PerformanceTest v10.0 Build 1008. The kernel driver exposes IOCTL functionality that allows low-privilege users to map arbitrary physical memory into the address space of the calling process. This cou...

Pixar OpenUSD binary file format offset seek information leak vulnerability

Summary An exploitable vulnerability exists in the way Pixar OpenUSD 20.05 handles file offsets in binary USD files. A specially crafted malformed file can trigger an arbitrary out-of-bounds memory access that could lead to the disclosure of sensitive information. This vulnerability could be used...

In core_info_read and inst_info_read in all Android releases from CAF using the Linux kernel variable "dbg_buf" "dbg_buf->curr" and "dbg_buf->filled_size" could be modified by different threads at the same time but they are not protected with mutex or locks. Buffer overflow is possible on race conditions. "buffer->curr" itself could also be overwritten which means that it may point to anywhere of kernel memory (for write).

CVE-2019-9813

Incorrect handling of proto mutations may lead to type confusion in IonMonkey JIT code and can be leveraged for arbitrary memory read and write. This vulnerability affects Firefox 66.0.1, Firefox ESR 60.6.1, and Thunderbird 60.6.1...

CVE-2020-8904 Arbitrary trusted memory overwrite vulnerability in Asylo

An arbitrary memory overwrite vulnerability in the trusted memory of Asylo exists in versions prior to 0.6.0. As the ecallrestore function fails to validate the range of the outputlen pointer, an attacker can manipulate the tmpoutputlen value and write to an arbitrary location in the trusted...

CVE-2020-14979

The WinRing0.sys and WinRing0x64.sys drivers 1.2.0 in EVGA Precision X1 through 1.0.6 allow local users, including low integrity processes, to read and write to arbitrary memory locations. This allows any user to gain NT AUTHORITY\SYSTEM privileges by mapping \Device\PhysicalMemory into the calli...
