Descripción técnica

schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the URL path concatenation and encoding module. The application splices untrusted extension path and attacker-controlled query string into a path buffer, then invokes urlencode without validating the final string length. Remote attackers can construct an oversized malicious URL path and query string to trigger out-of-bounds heap write, resulting in arbitrary code execution, information disclosure, service crash, or privilege escalation.

——0In 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.16h CVE-2026-512748.8 ALT

——0In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow in the ID3v2 SYLT synchronized lyrics parser in audiolib allows remote attackers to cause a denial of service (application crash), information disclosure, or potential arbitrary code execution via a crafted MP3 file. The vulnerability occurs due to missing bounds validation on attacker-controlled frame size and improper memory access during lyric parsing.16h CVE-2026-512737.8 ALT

——0In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow vulnerability exists in the ID3 tag parsing function showID3Tag() of the embedded audio streaming library. The program reads untrusted long ID3 tag value from malicious audio files and uses unbounded appendf() to write formatted strings into ps_ptr heap buffer without length validation. Successful exploitation allows attackers to execute arbitrary code, leak sensitive memory data, cause device crash, or escalate privileges via a crafted malicious audio file.16h CVE-2026-512719.6 CRÍ

——0In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow vulnerability exists in the WAV header parsing function read_WAV_Header(). The function reads untrusted chunk size and bytes-to-skip value directly from malicious WAV files without reasonable range restriction. Abnormally large bts and headerSize values lead to out-of-bounds heap memory read/write during header parsing, which can be exploited to execute arbitrary code, disclose sensitive information, cause denial of service or escalate privileges.17h CVE-2026-512698.8 ALT

——0schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the connecttospeech() function. The application accepts attacker-controlled long speech text input, performs URL encoding, and directly appends the encoded result into a fixed ps_ptr heap buffer when constructing HTTP TTS request headers. Lack of input length validation and boundary checking allows remote attackers to craft oversized input to trigger out-of-bounds heap write, resulting in arbitrary code execution.18h
