Detailsinfo

A vulnerability was found in zephyrproject-rtos zephyr 2.1.x (Project Management Software) and classified as critical. This issue affects the function updatehub_probe of the component JSON Parser. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In updatehub_probe, right after JSON parsing is complete, objects\[1] is accessed from the output structure in two different places. If the JSON contained less than two elements, this access would reference unitialized stack memory. This could result in a crash, denial of service, or possibly an information leak. Recommend disabling updatehub until such a time as a fix can be made available. Provided the fix in CVE-2020-10059 is applied, the attack requires compromise of the server.
