Name of the Vulnerable Software and Affected Versions GPAC versions 0.7.1 and earlier

Description The issue is related to the gf text get utf8 line function in the GPAC multimedia platform, which allows an out-of-bounds write due to missing bounds checking for szLineConv. This can potentially impact the confidentiality, integrity, and availability of protected information.
