The attached debdiff for minizip fixes CVE-2023-45853 in Bookworm. This
CVE has been marked as no-dsa by the security team.
Chrome upstream added a test for their internal copy of minizip. Running
this test against libminizip1 of this package worked as well, so I don't
expect any problems.

+ Reject overflows of zip header fields in minizip.
+
+ This checks the lengths of the file name, extra field, and comment
+ that would be put in the zip headers, and rejects them if they are
+ too long. They are each limited to 65535 bytes in length by the zip
+ format. This also avoids possible buffer overflows if the provided
+ fields are too long.
