Belangrijkste wijzigingen:<\/p>\n<ul>\n<li class=\"l\">Een kwetsbaarheid is verholpen, waardoor een aanvaller die de gebruikersnaam aanstuurt die wordt doorgegeven bij het starten van de ssh-tool, mogelijk willekeurige shell-opdrachten kan uitvoeren. De kwetsbaarheid doet zich voor in systemen die de substitutie &#171;%u&#187; gebruiken in bepaalde richtlijnen van het configuratiebestand, zoals &#171;Match exec&#187;. Het probleem wordt veroorzaakt door de controle van speciale karakters in de gebruikersnaam in een fase na de uitvoering van %-substituties in het ssh_config-configuratiebestand.<\/li>\n<li class=\"l\">Een beveiligingsprobleem in sshd is aangepakt, veroorzaakt door onjuiste vergelijking van de optie authorized_keys principals=&#187;&#187; met de lijst van namen (principal) in het certificaat in scenario's waarin de namen het teken &#171;,&#187; bevatten. Voor het misbruik van deze kwetsbaarheid moet in de optie authorized_keys principals=&#187;&#187; meerdere namen zijn opgegeven en moet de certificeringsinstantie een certificaat hebben afgegeven met meerdere namen, gescheiden door een komma (wat meestal niet is toegestaan). Het gedrag met betrekking tot certificaten met een lege naam is gewijzigd - eerder viel een lege naam onder alle opties van authorized_keys principals=&#187;&#187;, en nu valt deze daar niet meer onder.<\/li>\n<li class=\"l\">In scp is een probleem verholpen waardoor de setuid\/setgid-vlaggen niet werden gewist na het uploaden van een bestand met root-rechten met de optie &#171;-O&#187; en zonder de optie &#171;-p&#187;.<\/li>\n<li class=\"l\">In sshd is een probleem verholpen met de verwerking van ECDSA-sleutels in de richtlijnen PubkeyAcceptedAlgorithms en HostbasedAcceptedAlgorithms, waardoor bij opgave van een ECDSA-algoritme (zoals &#171;ecdsa-sha2-nistp384&#187;) ook alle andere algoritmen op basis van ECDSA werden geaccepteerd, zelfs als deze niet expliciet in de lijst van toegestane algoritmen stonden.<\/li>\n<li class=\"l\">In ssh en sshd is ondersteuning toegevoegd voor identificeerders (codepoint) die door IANA zijn gedefinieerd in de specificatie draft-ietf-sshm-ssh-agent. Ondersteuning voor eerder gebruikte identificeerders van het type &#171;@openssh.com&#187; is behouden.<\/li>\n<li class=\"l\">In ssh-agent is de &#171;query&#187;-uitbreiding ge\u00efmplementeerd, zoals gedefinieerd in de specificatie draft-ietf-sshm-ssh-agent, waarmee de door de agent ondersteunde functies kunnen worden bepaald. Voor het opvragen van de lijst met ondersteunde protocoluitbreidingen via de &#171;query&#187;-aanroep is de optie &#171;-Q&#187; aan het ssh-add-gereedschap toegevoegd.<\/li>\n<li class=\"l\">In sshd_config is het nu toegestaan om meerdere bestanden op te geven in de richtlijn RevokedKeys, terwijl in ssh_config dit geldt voor de richtlijn RevokedHostKeys.<\/li>\n<li class=\"l\">In ssh is added the escape command &#171;~I&#187; and the option &#171;-O conninfo&#187; to show information about the current connection, as well as the option &#171;-O channels&#187; to show information about open channels.<\/li>\n<li class=\"l\">In sshd, the PerSourcePenalties directive has been implemented with the option \u2018invaliduser\u2019 to add a delay in case of login attempts by a non-existent user (default is 5 seconds). It is now possible to specify non-integer delay values.<\/li>\n<li class=\"l\">In sshd, the GSSAPIDelegateCredentials option is added to manage the acceptance of delegated credentials provided by the client.<\/li>\n<li class=\"l\">In ssh-keygen, support for recording ED25519 keys in PKCS8 format has been added.<\/li>\n<li class=\"l\">Support for the ed25519 digital signature scheme has been implemented through libcrypto.<\/li>\n<\/ul>\n<p>Bron: <a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=65126\">opennet.ru<\/a><\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u043e\u0441\u043b\u0435 \u043f\u043e\u043b\u0443\u0433\u043e\u0434\u0430 \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u043a\u0438 \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0432\u044b\u043f\u0443\u0441\u043a OpenSSH 10.3, \u043e\u0442\u043a\u0440\u044b\u0442\u043e\u0439 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0438 \u043a\u043b\u0438\u0435\u043d\u0442\u0430 \u0438 \u0441\u0435\u0440\u0432\u0435\u0440\u0430 \u0434\u043b\u044f \u0440\u0430\u0431\u043e\u0442\u044b \u043f\u043e \u043f\u0440\u043e\u0442\u043e\u043a\u043e\u043b\u0430\u043c SSH 2.0 \u0438 SFTP. \u041e\u0441\u043d\u043e\u0432\u043d\u044b\u0435 \u0438\u0437\u043c\u0435\u043d\u0435\u043d\u0438\u044f: \u0423\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u0430 \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u044c, \u043f\u043e\u0437\u0432\u043e\u043b\u044f\u044e\u0449\u0430\u044f \u0430\u0442\u0430\u043a\u0443\u044e\u0449\u0435\u043c\u0443, \u043a\u043e\u043d\u0442\u0440\u043e\u043b\u0438\u0440\u0443\u044e\u0449\u0435\u043c\u0443 \u0438\u043c\u044f \u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u044f, \u043f\u0435\u0440\u0435\u0434\u0430\u0432\u0430\u0435\u043c\u043e\u0435 \u043f\u0440\u0438 \u0437\u0430\u043f\u0443\u0441\u043a\u0435 \u0443\u0442\u0438\u043b\u0438\u0442\u044b ssh, \u043f\u043e\u0442\u0435\u043d\u0446\u0438\u0430\u043b\u044c\u043d\u043e \u0434\u043e\u0431\u0438\u0442\u044c\u0441\u044f \u0432\u044b\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u044f \u043f\u0440\u043e\u0438\u0437\u0432\u043e\u043b\u044c\u043d\u044b\u0445 shell-\u043a\u043e\u043c\u0430\u043d\u0434. \u0423\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u044c \u043f\u0440\u043e\u044f\u0432\u043b\u044f\u0435\u0442\u0441\u044f \u0432 \u0441\u0438\u0441\u0442\u0435\u043c\u0430\u0445, \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u0443\u044e\u0449\u0438\u0445 \u043f\u043e\u0434\u0441\u0442\u0430\u043d\u043e\u0432\u043a\u0443 &#171;%u&#187; \u0432 \u043d\u0435\u043a\u043e\u0442\u043e\u0440\u044b\u0445 \u0434\u0438\u0440\u0435\u043a\u0442\u0438\u0432\u0430\u0445 \u0444\u0430\u0439\u043b\u0430 \u043a\u043e\u043d\u0444\u0438\u0433\u0443\u0440\u0430\u0446\u0438\u0438, \u0442\u0430\u043a\u0438\u0445 \u043a\u0430\u043a &#171;Match exec&#187;.
