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.

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.

PhysicsFS versions up to 3.2.0 contain an out-of-bounds read vulnerability in the __PHYSFS_utf8codepoint() function. This flaw allows attackers to read beyond buffer boundaries by exploiting an off-by-one cursor advance on six-octet UTF-8 sequences in archive entry names. Crafted archives with such names can cause over-read and potentially crash applications using PhysicsFS.
