Description Andrej Nemec 2017-05-19 14:20:32 UTC 
CVE-2017-9078 - The server in Dropbear before 2017.75 might allow post-authentication
root remote code execution because of a double free in cleanup of TCP
listeners when the -a option is enabled.

CVE-2017-9079 - Dropbear before 2017.75 might allow local users to read certain files
as root, if the file has the authorized_keys file format with a
command= option. This occurs because ~/.ssh/authorized_keys is read
with root privileges and symlinks are followed.
