Thanks for reporting this, Ilya. Can you please elaborate about the potential impact of this issue - that 'inflate() does not update strm.adler if DFLTCC is used'? Especially because this is marked with severity medium, but the Ubuntu stable release update process (SRUs: https://wiki.ubuntu.com/StableReleaseUpdates) is generally in order to fix high-impact bugs. With updating stable releases (like in this case 20.04 and 22.04) there is huge carefulness needed, and especially with updating key packages and libraries like zlib, since zlib has significant package reverse dependencies and a huge amount of reverse build dependencies (both in the thousands). Furthermore a potential update will impact multi-millions of installations, cross architecture, and we won't do that for a non-critical bugs, that maybe even only impact a small number of installations. However, there might be a little chance to piggy-back a fix like this with a more severe zlib update that might come up in future.
