Name of the Vulnerable Software and Affected Versions: GPAC version 1.0.1

Description: The issue is related to an integer overflow in the gf props assign value function, located in filter core/filter props.c. This overflow occurs when the value->value.data.size is a negative number, causing the memcpy in gf props assign value to fail.

Recommendations: For GPAC version 1.0.1, as a temporary workaround, consider restricting the use of the gf props assign value function until a patch is available. Additionally, ensure that the value->value.data.size is validated to prevent negative numbers. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
