Description
Updated dropbear packages fix security vulnerability Message printout was vulnerable to format string injection. If specific usernames including "%" symbols can be created on a system (validated by getpwnam()) then an attacker could run arbitrary code as root when connecting to Dropbear server. Also, a dbclient user who can control username or host arguments could potentially run arbitrary code as the dbclient user. This could be a problem if scripts or webpages pass untrusted input to the dbclient program (CVE-2016-7406). dropbearconvert import of OpenSSH keys could run arbitrary code as the local dropbearconvert user when parsing malicious key files (CVE-2016-7607). dbclient could run arbitrary code as the local dbclient user if particular -m or -c arguments are provided. This could be an issue where dbclient is used in scripts (CVE-2016-7408).
