CVSS: 8.0EPSS: 0%CPEs: 1EXPL: 0CVE-2020-10060 – UpdateHub Might Dereference An Uninitialized Pointer
https://notcve.org/view.php?id=CVE-2020-10060
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. Provided the fix in CVE-2020-10059 is applied, the attack requires compromise of the server.
