From 737ede405b11a37fdd61d19cf25df296a0cb0b75
From: Cosmin Stejerean <cosmin@cosmin.at>
Date: Wed Dec 6 18:39:32 2023 +0800
Subject: avfilter/bwdif: account for chroma sub-sampling in min size calculation
References: https://bugzilla.opensuse.org/1223235
References: CVE-2023-49502
The current logic for detecting frames that are too small for the
algorithm does not account for chroma sub-sampling, and so a sample
where the luma plane is large enough, but the chroma planes are not
will not be rejected. In that event, a heap overflow will occur.
This change adjusts the logic to consider the chroma planes and makes
the change to all three bwdif implementations.
Fixes #10688
