NVD Description

Note: Versions mentioned in the description apply only to the upstream smpeg package and not the smpeg package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

smpeg through 2.0.0 contains an integer underflow vulnerability in stream_header() in MPEGsystem.cpp that allows attackers to wrap packet_size by declaring an undersized packet length. Attackers can supply a crafted MPEG file opened via SMPEG_new, SMPEG_new_rwops or SMPEG_new_data to trigger a reachable assertion or out-of-bounds copy, crashing the application.
