FFmpeg decode_plane Function Denial Of Service Vulnerability

A vulnerability in FFmpeg could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a targeted system.

The vulnerability exists in the decode_plane function, defined in the libavcodec/utvideodec.c source code file of the affected software, and is due to insufficient validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by submitting a crafted AVI file to a targeted system. A successful exploit could cause an out-of-array read on the targeted system, which could result in a DoS condition on the targeted system.

The vendor has confirmed the vulnerability and released software updates.

  • To exploit this vulnerability, the attacker may need to submit a crafted AVI file to the targeted system, which is more difficult in environments that restrict network access from untrusted sources.
  • Administrators are advised to apply the appropriate updates.

    Administrators are advised to allow only trusted users to have network access.

    Administrators can help protect affected systems from external attacks by using a solid firewall strategy.

    Administrators are advised to monitor affected systems.
