| Name | CVE-2023-45853 |
| Description | MiniZip in zlib through 1.3 has an integer overflow and resultant heap-based buffer overflow in zipOpenNewFileInZip4_64 via a long filename, comment, or extra field. NOTE: MiniZip is not a supported part of the zlib product. NOTE: pyminizip through 0.2.6 is also vulnerable because it bundles an affected zlib version, and exposes the applicable MiniZip code through its compress API. |

Notes
[bookworm] - zlib <ignored> (contrib/minizip not built and src:zlib not producing binary packages)
[bullseye] - zlib <ignored> (contrib/minizip not built and src:zlib not producing binary packages)
[buster] - zlib <ignored> (contrib/minizip not built and src:zlib not producing binary packages)

https://github.com/madler/zlib/commit/73331a6a0481067628f065ffe87bb1d8f787d10c
src:zlib only starts building minizip starting in 1:1.2.13.dfsg-2
For older suites due to this an update can be ignored as no binary package built
by the vulnerable source is affected (i.e. contrib/minizip not built and provided
in those versions).
