dropbear: security bump to version 2017.75
Fixes:
- CVE-2017-9078: 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. Affects versions 2013.56 to
2016.74. Thanks to Mark Shepard for reporting the crash.
- CVE-2017-9079: Dropbear parsed authorized_keys as root, even if it were a
symlink. The fix is to switch to user permissions when opening
authorized_keys.
A user could symlink their ~/.ssh/authorized_keys to a root-owned file
they couldn't normally read. If they managed to get that file to contain
valid authorized_keys with command= options it might be possible to read
other contents of that file. This information disclosure is to an already
authenticated user. Thanks to Jann Horn of Google Project Zero for
reporting this.
