CVE-2021-38165:

Lynx through 2.8.9 mishandles the userinfo subcomponent of a URI, which allows remote attackers to discover cleartext credentials because they may appear in SNI data.

Fix is in 2.9.0dev.9.

Let's give it a little time to stew.

Note the ebuild maps pre ebuilds to upstream's dev releases:

case ${PV} in
    *_pre*) MY_P="${PN}${PV/_pre/dev.}" ;;
    *_rc*)  MY_P="${PN}${PV/_rc/pre.}" ;;
    *_p*|*) MY_P="${PN}${PV/_p/rel.}" ;;
