Vulnerabilidades

Potential security vulnerabilities have been identified in the BIOS (UEFI Firmware) for certain HP PC products, which might allow arbitrary code execution. HP is releasing firmware updates to mitigate these potential vulnerabilities.

HP has identified a potential vulnerability in BIOS firmware of some Workstation products. Firmware updates are being released to mitigate these potential vulnerabilities.

Dell BIOS contains a Stack based buffer overflow vulnerability. A local authenticated attacker could potentially exploit this vulnerability by using an SMI to send larger than expected input to a parameter to gain arbitrary code execution in SMRAM.

Dell BIOS contains a Time-of-check Time-of-use vulnerability. A local authenticated malicious user could\u00a0potentially exploit this vulnerability by using a specifically timed DMA transaction during an SMI to gain arbitrary code execution on the system.

Dell BIOS contains a heap buffer overflow vulnerability. A local attacker with admin privileges could potentially exploit this vulnerability to perform an arbitrary write to SMRAM during SMM.

Realtek Audio Drivers for Windows, as used on the Lenovo ThinkPad X1 Carbon 20A7, 20A8, 20BS, and 20BT before 6.0.8882.1 and 20KH and 20KG before 6.0.8907.1 (and on many other Lenovo and non-Lenovo products), mishandles DLL preloading.

A potential vulnerability has been identified in the system BIOS for certain HP PC products which may allow escalation of privileges and code execution. HP is releasing firmware updates to mitigate the potential vulnerability.

A potential security vulnerability has been identified in certain HP Workstation BIOS (UEFI firmware) which may allow arbitrary code execution. HP is releasing firmware mitigations for the potential vulnerability.

A Memory Allocation with Excessive Size Value vulnerablity in the TEE_Realloc function in Samsung mTower through 0.3.0 allows a trusted application to trigger a Denial of Service (DoS) by invoking the function TEE_Realloc with an excessive number for the parameter len.

The function tee_obj_free in Samsung mTower through 0.3.0 allows a trusted application to trigger a Denial of Service (DoS) by invoking the function TEE_AllocateOperation with a disturbed heap layout, related to utee_cryp_obj_alloc.

A Buffer Access with Incorrect Length Value vulnerablity in the TEE_MACUpdate function in Samsung mTower through 0.3.0 allows a trusted application to trigger a Denial of Service (DoS) by invoking the function TEE_MACUpdate with an excessive size value of chunkSize.

A NULL pointer dereference issue in the TEE_MACCompareFinal function in Samsung mTower through 0.3.0 allows a trusted application to trigger a Denial of Service (DoS) by invoking the function TEE_MACCompareFinal with a NULL pointer for the parameter operation.

A Buffer Access with Incorrect Length Value vulnerablity in the TEE_CipherUpdate function in Samsung mTower through 0.3.0 allows a trusted application to trigger a Denial of Service (DoS) by invoking the function TEE_CipherUpdate with an excessive size value of srcLen.

A Buffer Access with Incorrect Length Value vulnerablity in the TEE_MACComputeFinal function in Samsung mTower through 0.3.0 allows a trusted application to trigger a Denial of Service (DoS) by invoking the function TEE_MACComputeFinal with an excessive size value of messageLen.

Dell BIOS versions contain a Stack-based Buffer Overflow vulnerability. A local authenticated malicious user could potentially exploit this vulnerability by sending excess data to a function in order to gain arbitrary code execution on the system.
