Name of the Vulnerable Software and Affected Versions json-c versions 0.14 through 0.15-20200726

Description A stack-buffer-overflow issue exists in the json parse auxiliary sample program, specifically in the parseit function. This issue is related to a buffer overflow in memory, which can be exploited by a remote attacker to execute arbitrary code.

Recommendations For json-c versions 0.14 through 0.15-20200726, consider disabling the parseit function as a temporary workaround until a patch is available. Restrict access to the json parse auxiliary sample program to minimize the risk of exploitation.
