This is to report that CVE is detected during u-boot scanning. Sending to open mailing list as get_maintainer suggested.
The current zlib version used in u-boot contains CVE-2018-25032 [1]. Corresponding fix in zlib mainline has been addressed in v1.2.12 [2]. It is required to upgrade zlib in u-boot to that version or later to mitigate the CVE.

Please note that by default, no U-Boot binary is vulnerable to this as we only support using the zlib deflate (so, compress a file, not uncompress an archive) when CMD_ZIP is enabled. This is only true of the sandbox build.
A patch to apply the fix from upstream would be most welcome, all the same. Thanks!
