Summary
Juniper heeft meerdere kwetsbaarheden verholpen in Junos OS en Junos OS Evolved, specifiek voor MX Series, PTX Series, QFX Series, EX Series, SRX Series en QFX10000 Series apparaten.
Details
Interpretaties
De kwetsbaarheden betreffen verschillende componenten binnen Junos OS en Junos OS Evolved, waaronder de packet forwarding engine, routing protocol daemon, management daemon, SNMP daemon, http-gatekeeper, TCP proxy plugin, IKE daemon, fileio library, SIP plugin, URL filtering plugin en CLI. Exploitatie kan leiden tot geheugenbeschadiging, crashes van processen zoals mgd, rpd, flow processing daemon, l2ald, en FPC, wat resulteert in Denial-of-Service (DoS) condities. Sommige kwetsbaarheden kunnen door lokale gebruikers met beperkte rechten worden misbruikt om code uit te voeren of processen te laten crashen. Andere kwetsbaarheden kunnen door niet-geauthenticeerde aanvallers via netwerkverkeer worden misbruikt om processen te laten crashen, informatie te lekken, licentie-uitputting te veroorzaken of firewallregels te omzeilen. Specifieke hardwaremodellen en softwareversies zijn getroffen, zoals MX Series met SPC3, SRX Series, EX Series (EX2300, EX4000, EX4100, EX4400), QFX Series, PTX Series en QFX10000 Series. Sommige kwetsbaarheden vereisen handmatige herstart van systemen of processen om normale werking te herstellen. De problemen zijn aanwezig in versies voorafgaand aan de gepubliceerde patches en updates.
