Changes:
 aom (3.12.1-1+deb13u1) trixie-security; urgency=high
 .
   * Non-maintainer upload by the Security Team.
   * Backport upstream security fixes for four encoder vulnerabilities.
     - debian/patches/0004-CVE-2026-56209-56210-56211-svc-layer-id-bounds-check.patch:
       Validate the spatial and temporal layer ids passed to the
       AOME_SET_SPATIAL_LAYER_ID and AV1E_SET_SVC_LAYER_ID codec controls
       against the configured number of layers.
       Fixes: CVE-2026-56210, CVE-2026-56209 and CVE-2026-56211.
     - debian/patches/0005-CVE-2026-56208-lap-stats-buffer-overflow.patch:
       Size the first-pass stats buffer to at least MAX_GF_LENGTH_LAP + 1, use
       a compacting sliding window in Look-Ahead Processing mode and correct an
       off-by-one in the rest_frames computation, fixing an out-of-bounds
       access to the first-pass stats array triggered by a small
       g_lag_in_frames (CVE-2026-56208).
   * debian/patches/0006-svc-add-more-spatial-temporal-layer-validation.patch:
     Reject SVC spatial and temporal layer counts outside the supported range
     in AOME_SET_NUMBER_SPATIAL_LAYERS and AV1E_SET_SVC_PARAMS, and report an
     invalid parameter rather than relying on an assert() for the fixed-SVC
     layer count limit. This is a pre-existing out-of-bounds access in 3.12.1,
     included here because the layer id validation added above derives its
     bounds from these counts.
