{"id":"MGASA-2016-0301","summary":"Updated dropbear packages fix security vulnerability","details":"Message printout was vulnerable to format string injection.\n\nIf specific usernames including \"%\" symbols can be created on a system\n(validated by getpwnam()) then an attacker could run arbitrary code as\nroot when connecting to Dropbear server. Also, a dbclient user who can\ncontrol username or host arguments could potentially run arbitrary code\nas the dbclient user. This could be a problem if scripts or webpages\npass untrusted input to the dbclient program (CVE-2016-7406).\n\ndropbearconvert import of OpenSSH keys could run arbitrary code as the\nlocal dropbearconvert user when parsing malicious key files\n(CVE-2016-7607).\n\ndbclient could run arbitrary code as the local dbclient user if\nparticular -m or -c arguments are provided. This could be an issue where\ndbclient is used in scripts (CVE-2016-7408).\n","modified":"2026-04-16T01:47:18.362025329Z","published":"2016-09-16T09:27:13Z","upstream":["CVE-2016-7406","CVE-2016-7407","CVE-2016-7408"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2016-0301.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=19074"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2016/09/15/2"},{"type":"WEB","url":"https://secure.ucc.asn.au/hg/dropbear/rev/10f28c95ca31"}],"affected":[{"package":{"name":"dropbear","ecosystem":"Mageia:5","purl":"pkg:rpm/mageia/dropbear?arch=source&distro=mageia-5"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2014.66-1.2.mga5"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2016-0301.json"}}],"schema_version":"1.7.5","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
