Subject: [PATCH] jpeg: Be more careful with chunked icc data
We we inadvertendly trusting the sequence numbers not to lie.
If they do we would report a larger data size than we actually
allocated, leading to out of bounds memory access in base64
encoding later on.
This has been assigned CVE-2025-7345.
Fixes: #249
