The first one has different exposure for client/server parts so I assume it should have separate CVEs? Cheers, Matt (please CC replies) 2016.74 - 21 July 2016 - Security: 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. 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. https://secure.ucc.asn.au/hg/dropbear/rev/b66a483f3dcb - Security: dropbearconvert import of OpenSSH keys could run arbitrary code as the local dropbearconvert user when parsing malicious key files https://secure.ucc.asn.au/hg/dropbear/rev/34e6127ef02e - Security: 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. https://secure.ucc.asn.au/hg/dropbear/rev/eed9376a4ad6 - Security: dbclient or dropbear server could expose process memory to the running user if compiled with DEBUG_TRACE and running with -v https://secure.ucc.asn.au/hg/dropbear/rev/6a14b1f6dc04 The security issues were reported by an anonymous researcher working with Beyond Security's SecuriTeam Secure Disclosure www.beyondsecurity.com/ssd.html
