60931f98-55a7-11e7-8514-589cfc0654e1 | Dropbear -- two vulnerabilities
Matt Johnston reports:
Fix double-free in server TCP listener cleanup A double-free in
the server could be triggered by an authenticated user if dropbear
is running with -a (Allow connections to forwarded ports from any
host) This could potentially allow arbitrary code execution as root
by an authenticated user.
Fix information disclosure with ~/.ssh/authorized_keys symlink.
Dropbear parsed authorized_keys as root, even if it were a symlink.
The fix is to switch to user permissions when opening authorized_keys.

bc19dcca-7b13-11e6-b99e-589cfc0654e1 | dropbear -- multiple vulnerabilities
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

eba70db4-6640-11e1-98af-00262d8b701d | dropbear -- arbitrary code execution
The Dropbear project reports:
Dropbear SSH Server could allow a remote authenticated attacker
to execute arbitrary code on the system, caused by a use-after-
free error. If a command restriction is enforced, an attacker
could exploit this vulnerability to execute arbitrary code on
the system with root privileges.
