Description
A vulnerability has been found in GPAC up to 26.07.0. This vulnerability affects the function gf_m2ts_decode_ait of the file src/media_tools/ait.c of the component AIT Parser. Such manipulation leads to out-of-bounds write. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The name of the patch is 6d2c21a1a688abb20d0111b608db3b6f44d348f4. Applying a patch is advised to resolve this issue.
A heap buffer overflow vulnerability has been identified in GPAC versions through 26.07.0, specifically within the AIT (Application Information Table) parser. The issue arises in the function 'gf_m2ts_decode_ait' located in 'src/media_tools/ait.c'. The vulnerability allows for an out-of-bounds write by manipulating the 'application_descriptors_id' array, which is intended to store descriptor tags. This array has a capacity of 50 bytes, but the parser can be tricked into writing far beyond this limit, leading to memory corruption. The vulnerability can be exploited remotely, and has been publicly disclosed along with a proof-of-concept.
Users are advised to update to GPAC version 26.08 or later, where this vulnerability has been fixed.
