Utgivelsen kjennetegnes hovedsakelig av feilrettinger, inkludert eliminering av flere potensielle s\u00e5rbarheter for\u00e5rsaket av problemer med minneh\u00e5ndtering:  <\/p>\n<ul>\n<li class=\"l\"> Ett-byte-overl\u00f8p i SSH-banneh\u00e5ndteringskoden i verkt\u00f8yet ssh-keyscan.\n<li class=\"l\"> Dobbelt kall av funksjonen free() ved feil under beregning av hasher for filer i koden for oppretting og verifisering av digitale signaturer i verkt\u00f8yet ssh-keygen.\n<li class=\"l\"> Dobbelt kall av funksjonen free() ved feilbehandling i verkt\u00f8yet ssh-keysign.    <\/ul>\n<p>Hovedendringer:  <\/p>\n<ul>\n<li class=\"l\"> I ssh og sshd er direktivet RequiredRSASize lagt til, som definerer minimum tillatt st\u00f8rrelse p\u00e5 RSA-n\u00f8kler. N\u00f8kler som er mindre i sshd blir ignorert, og i ssh f\u00f8rer det til avslutning av forbindelsen.\n<li class=\"l\"> Den b\u00e6rbare utgaven av OpenSSH er overf\u00f8rt til \u00e5 bruke SSH-n\u00f8kler for \u00e5 autentisere digitale signaturer for commits og tags i Git.\n<li class=\"l\"> Direktivene SetEnv i konfigurasjonsfilene ssh_config og sshd_config bruker n\u00e5 verdien fra den f\u00f8rste forekomsten av milj\u00f8variabelen, hvis den er definert i konfigurasjonen flere ganger (tidligere ble den siste forekomsten brukt).\n<li class=\"l\"> N\u00e5r du kaller programmet ssh-keygen med flagget &#171;-A&#187; (generering av alle standard st\u00f8ttede typer verts-n\u00f8kler), er generering av DSA-n\u00f8kler deaktivert, da de ikke har v\u00e6rt i bruk som standard p\u00e5 flere \u00e5r.\n<li class=\"l\"> Utvidelsen &#171;users-groups-by-id@openssh.com&#187; er implementert i sftp-server og sftp, og gir klienten mulighet til \u00e5 foresp\u00f8rre brukernavn og gruppenavn som tilsvarer et angitt sett med numeriske identifikatorer (uid og gid). I sftp er denne utvidelsen brukt for \u00e5 vise navn ved oppf\u00f8ring av innholdet i katalogen.\n<li class=\"l\"> Utvidelsen &#171;home-directory&#187; er implementert i sftp-server for \u00e5
