Subject: [PATCH] coap_oscore.c: Fix parsing OSCORE configuration information
|
||||
|
||||
A vulnerability was found in obgm libcoap 4.3.4. It has been rated as critical.
|
||||
Affected by this issue is the function get_split_entry of the file src/coap_oscore.c of the component Configuration File Handler.
|
||||
The manipulation leads to stack-based buffer overflow.
