CVE-2021-36368
Desc: ** DISPUTED ** An issue was discovered in OpenSSH before 8.9. If a client is using public-key authentication with agent forwarding but without -oLogLevel=verbose, and an attacker has silently modified the server to support the None authentication option, then the user cannot determine whether FIDO authentication is going to confirm that the user wishes to connect to that server, or that the user wishes to allow that server to connect to a different server on the user's behalf. NOTE: the vendor's position is "this is not an authentication bypass, since nothing is being bypassed."

Severity: LOW
CVE-2021-41617
Desc: sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user.

********** QA ADVISORY **********

CVE-2021-36368:

Патч на исправление уязвимости апстрим не принял и не планирует.
Версия 8.9, неподверженная данной уязвимости, не собирается на e2k из-за --with-sandbox=seccomp_filter, seccomp_filter не поддерживается.
8.8p1 собирался с --with-sandbox=rlimit, на 8.9 следующая ошибка:
  configure: error: rlimit sandbox requires select to work with rlimit

Учитывая серьезность уязвимости LOW предлагаю в 2021.1 пока оставить как есть.



CVE-2021-41617 - не актуальна для версии 8.8, стало быть для порта 8.8p1 тоже.
