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.
