+ <p>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.
+
+ 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.</p>
+ <p>dropbearconvert import of OpenSSH keys could run arbitrary code as
+ the local dropbearconvert user when parsing malicious key files.</p>
+ <p>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.</p>
+ <p>dbclient or dropbear server could expose process memory to the
+ running user if compiled with DEBUG_TRACE and running with -v</p>
