Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

DOS / potential heap overwrite in mkv demuxing using HEADERSTRIP decompression. Integer overflow in matroskaparse element in gst_matroska_decompress_data function which causes a heap overflow. Due to restrictions on chunk sizes in the matroskademux element, the overflow can't be triggered, however the matroskaparse element has no size checks.
