Micrium OS Network uC-HTTP server header parsing invalid pointer dereference vulnerability

A bug in Micrium OS Network HTTP Server permits an invalid pointer dereference during header processing - potentially allowing a device crash and Denial of Service.

A memory corruption vulnerability exists in the HTTP Server Host header parsing functionality of Weston Embedded uC-HTTP v3.01.01. A specially crafted network packet can lead to code execution. An attacker can send a malicious packet to trigger this vulnerability.

A heap-based buffer overflow vulnerability exists in the HTTP Server form boundary functionality of Weston Embedded uC-HTTP v3.01.01. A specially crafted network packet can lead to code execution. An attacker can send a malicious packet to trigger this vulnerability.

A heap-based buffer overflow vulnerability exists in the HTTP Server functionality of Weston Embedded uC-HTTP git commit 80d4004. A specially crafted network packet can lead to arbitrary code execution. An attacker can send a malicious packet to trigger this vulnerability.

Unvalidated input in Silicon Labs TrustZone implementation leads to accessing Trusted memory region

An unvalidated input in Silicon Labs TrustZone implementation in v4.3.x and earlier of the Gecko SDK allows an attacker to access the trusted region of memory from the untrusted region.

Glitch detection not active by default in Silicon Labs Secure Vault High devices

Glitch detection is not enabled by default for the CortexM33 core in Silicon Labs secure vault high parts EFx32xG2xB, except EFR32xG21B.

Incorrect buffer parsing in Bluetooth LE sample code may lead to buffer overflow

A potential buffer overflow exists in the Bluetooth LE HCI CPC sample application in the Gecko SDK which may result in a denial of service or remote code execution

Malformed Zigbee packet with invalid destination address causes Assert

 A malformed packet containing an invalid destination address, causes a stack overflow in the Ember ZNet stack. This causes an assert which leads to a reset, immediately clearing the error.

Potential Timing vulnerability in CBC PKCS7 padding calculations

An Observable Timing Discrepancy, Covert Timing Channel vulnerability in Silabs GSDK on ARM potentially allows Padding Oracle Crypto Attack on CBC PKCS7.This issue affects GSDK: through 4.4.0.

Bluetooth LE Invalid prepare write request command leads to denial of service

An invalid ‘prepare write request’ command can cause the Bluetooth LE stack to run out of memory and fail to be able to handle subsequent connection requests, resulting in a denial-of-service.

Uninitialized TRNG used for ECDSA after EM2/EM3 sleep for VSE devices

TRNG is used before initialization by ECDSA signing driver when exiting EM2/EM3 on Virtual Secure Vault (VSE) devices. This defect may allow Signature Spoofing by Key Recreation.This issue affects Gecko SDK through v4.4.0.

Silicon Labs EFR32 Bluetooth stack denial of service when sending notifications to multiple clients

A memory leak in the Silicon Labs' Bluetooth stack for EFR32 products may cause memory to be exhausted when sending notifications to multiple clients, this results in all Bluetooth operations, such as advertising and scanning, to stop.
