Matt Johnston reports:

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