smpeg through 2.0.0 Heap Out-of-Bounds Read via MPEGsystem::FillBuffer

Published Oct 18, 2026 CVSS 4.0 · 6.8 Medium EPSS < 1% KEV · Not listed
Description
smpeg through 2.0.0 contains a heap out-of-bounds read vulnerability in MPEGsystem::FillBuffer() that allows attackers to read past the 16384-byte buffer by supplying a crafted system header stream table. Attackers can provide an MPEG file whose stream table bytes all set the high bit, which crashes applications opening it through SMPEG_new, SMPEG_new_rwops, or SMPEG_new_data.
