FFmpeg Security Flaw: When “Evil” Plugins Attack!
The FFmpeg ladspa filter lets unsanitized environment variables dictate dynamic library loading. By tweaking LADSPA_PATH or $HOME, attackers can sneak in malicious .so files, executing arbitrary code with the innocence of a Trojan horse in a library. Always check your paths, or you might just get pwned.
Hot Take:
Who knew that while tuning up your audio with FFmpeg, you might accidentally be tuning into a hacker’s playlist of chaos? Time to hit pause on those unsanitized variables before your speakers start blasting “Pwned FM.”
Key Points:
- FFmpeg’s LADSPA filter is vulnerable due to unsanitized environment variables.
- Attackers can manipulate LADSPA_PATH and HOME to execute arbitrary code.
- Vulnerability affects FFmpeg versions 7.0 to 8.0 with –enable-ladspa.
- Exploitation can occur through malicious shared objects in specific directories.
- Proof of concept shows how attackers can pwn your FFmpeg process with a simple plugin.
