Name of the Vulnerable Software and Affected Versions GPAC version 26.03-DEV

Description An issue exists in the MP4Box component within the vobsub read idx() function of the /src/media tools/vobsub.c file. A local attacker can trigger an out-of-bounds read by manipulating the num langs argument. An out-of-bounds read occurs when a program reads data past the end of the intended buffer, potentially exposing sensitive information from memory.

Recommendations Apply the patch 532097084729a936bcdf6a27c41003f3bd7dc3ff to version 26.03-DEV.
