Solution:
All zlib users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=sys-libs/zlib-1.2.1-r3"
# emerge ">=sys-libs/zlib-1.2.1-r3"
You should also run revdep-rebuild to rebuild any packages that depend on
older versions of zlib :
# revdep-rebuild
Please note that any packages which have the zlib library compiled statically will not show up using revdep-rebuild.
You will need to locate those packages manually and then remerge them.
