Name of the Vulnerable Software and Affected Versions
stb vorbis versions prior to 1.23
Description
A heap buffer overflow occurs in the
start decoder() function due to the truncation of the codebook multiplicands allocation size from size t to int. An attacker can exploit this by providing a specially crafted Ogg Vorbis file containing large entries and dimensions values, leading to out-of-bounds writes. This can result in heap corruption or process crashes.Recommendations
Update to a version newer than 1.22.
