From zlib: Reject overflows of zip header fields in minizip. #427

Closed jayaddison closed 8 months ago

With the minizip code in the codebase updated by #420, it's fairly straightforward to cherry-pick a fixup for CVE-2023-45853.

If-and-when a release of zlib v1.3.1 (that contains minizip in the contrib directory) appears, it could be worthwhile to update to that; since that hasn't appeared yet I think it may make sense to apply this here directly.

Merged. Thanks.
