A vulnerability in GPAC could allow an unauthenticated, remote attacker to trigger a buffer overflow on a targeted system.The vulnerability is due to insufficient checks of the crypt feature in the gf_bin128_parse function, as defined by the utils/os_dirvers.c source code file of the affected software. An attacker could exploit this vulnerability by sending a crafted _drm_file.xml file to the affected software which could cause a buffer overflow on the targeted system.
