CVE-2026-125268

FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in the CineForm HD decoder that allows attackers to leak heap memory via unzeroed idwt_tmp buffers in libavcodec/cfhd.c. Attackers can supply a crafted CFHD file with an ImageHeight tag exceeding coded band heights, causing uninitialized heap bytes to be filtered into decoded video output.

Check the content

Check the version numbers before you commit this entry. Some ports share an entry in the CVE database with another port, such as sqlite2 and sqlite3. The version shown here may then be one that never existed for this port.

Ranges per package from the CVE rows that match this port, in pkg notation with the port's epoch and revision, every bound checked with pkg; one range per epoch the port actually had. make newentry in security/vuxml creates the vid.
