Name of the Vulnerable Software and Affected Versions stb vorbis (affected versions not specified)

Description The issue is related to the processing of ogg vorbis files. A crafted file can trigger an out of buffer write in the start decoder function. This occurs because the maximum value of m->submaps is 16, but the arrays submap floor and submap residue are declared with 15 elements. This can potentially lead to code execution.
