high
Description
In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow in the ID3v2 APIC frame parsing function in audiolib allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a crafted MP3 file. The vulnerability exists due to missing length validation when processing the APIC frame size field, leading to an out-of-bounds memory write.
