Vulnerabilities

In EmberZNet 9.1.1 and earlier, a malformed Simple_Desc_req response can result in an out-of-bounds write potentially leading to remote code execution.

In EmberZNet 9.1.1 and earlier, a malformed Publish Price Matrix command can result in an out-of-bounds write potentially leading to remote code execution.

In EmberZNet 9.1.1 and earlier, a malformed Publish Billing Period command can result in a recursive function call that will never reach its end condition.

In EmberZNet 9.1.1 and earlier, a malformed Discover Attributes command can result in a loop with unreachable exit condition (infinite loop).

In EmberZNet 9.1.1 and earlier, a malformed GetGroupMembership message can result in an out-of-bounds write leading to a crash.

In EmberZNet v9.0.2 and earlier, a malformed GetProfileResponse message can trigger out-of-bounds reads while iterating interval entries and terminate the process.

In EmberZNet v9.0.2 and earlier, a malformed Level Control Step command can terminate the process through a divide-by-zero fault.

In EmberZNet v9.0.2 and earlier, a malformed Level Control Move command can terminate the process through a divide-by-zero fault.

In EmberZNet v9.0.2 and earlier, malformed ClearWeekdaySchedule messages can trigger out-of-bounds writes into Door Lock schedule state.

In EmberZNet v9.0.2 and earlier, malformed IAS Zone enrollment messages can trigger an out-of-bounds state-table write and terminate the process.

In EmberZNet v9.0.2 and earlier, malformed or out-of-range Door Lock user identifiers can trigger out-of-bounds table reads and terminate the process.

In EmberZNet v9.0.2 and earlier, malformed GetGroupMembership commands can trigger repeated reads past the end of the message payload and terminate the process.

In EmberZNet v9.0.2 and earlier, malformed OTA requests can drive the OTA server parser into out-of-bounds reads.

In EmberZNet v9.0.2 and earlier, malformed Color Control messages can lead to asserts that terminate the process.

In EmberZNet v9.0.2 and earlier, malformed Color Control messages can lead to asserts that terminate the process.

In EmberZNet v9.0.2 and earlier, malformed global ZCL messages can trigger out-of-bounds reads in framework parsing logic and terminate the process.

Due to an allocation of resources without limits, an uncontrolled resource consumption vulnerability exists in Silicon Labs Ember ZNet SDK prior to v7.4.0.0 (delivered as part of Silicon Labs Gecko SDK v4.4.0) which may…

High traffic environments may result in NULL Pointer Dereference vulnerability in Silicon Labs's Ember ZNet SDK before v7.4.0, causing a system crash.

Ember ZNet between v7.2.0 and v7.4.0 used software AES-CCM instead of integrated hardware cryptographic accelerators, potentially increasing risk of electromagnetic and differential power analysis sidechannel attacks.

TouchLink packets processed after timeout or out of range due to Operation on a Resource after Expiration and Missing Release of Resource after Effective Lifetime may allow a device to be added outside of valid TouchLink…

A malformed packet causes a stack overflow in the Ember ZNet stack.

Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Silicon Labs Ember ZNet allows Overflow Buffers.
