543 Vulnerabilities in FFmpeg: Hunting Flaws in the Industry Standard

FFmpeg, the open-source library serving as the de facto standard for audio and video processing in mobile apps, carries approximately 543 registered CVEs that frequently appear in bug bounty programs. A Quokka report on over 150,000 applications found critical third-party CVEs in 11% of Android and 13% of iOS apps, with high-severity issues in 65% of Android applications. The article examines three notable vulnerabilities including PixelSmash (CVE-2026-8461), HTTP chunked overflow (CVE-2016-10190), and an AV1 RTP depacketizer flaw (DFVULN-127), each enabling remote code execution through memory corruption. It provides practical guidance on locating FFmpeg binaries inside APKs, identifying integration patterns, determining versions via strings and NDK timestamps, and extracting build configurations to confirm enabled components. Analysts are shown how to locate protocol handlers that serve as entry points without requiring malicious media files. The material targets reverse engineers experienced with ELF libraries and memory corruption issues.

Yandex Disk Data Center Incidents Leave Photos and Videos Inaccessible, Custom Recovery Tool Emerges

Following incidents at Yandex data centers in Sasovo and Vladimir, large numbers of photos and videos stored on Yandex Disk became unavailable for normal download. The company attributed the restrictions to load reduction, yet analysis indicates permanent loss of certain data clusters with no confirmed backups. Photos remain partially recoverable through lower-resolution S3 copies such as XXXL and XXL, while videos suffer from missing byte ranges that produce truncated or corrupted files. A researcher developed a specialized tool using mitmproxy to intercept browser requests and download available file variants in parallel streams. The utility also attempts block-by-block video retrieval to salvage whatever segments remain accessible. Users are warned that continued use of the tool may violate service terms and risk account suspension. The developer advises downloading data immediately rather than waiting for potential further degradation.
