CVE-2015-3436 [MEDIUM] CVE-2015-3436 zarafa: Overwrite arbitrary files in filesystem
CVE-2015-3436 zarafa: Overwrite arbitrary files in filesystem
Guido Günther detected and reported that replacing "/tmp/zarafa-upgrade-lock"
by a symlink makes the zarafa-server process following that symlink and thus
allows to overwrite arbitrary files in the filesystem (assuming zarafa-server
runs as root which is not case by default at Fedora, but upstream default).
One just needs write permissions in /tmp and wait until the zarafa-server is
restarted.
Discussion:
Zarafa fixed this issue with version 7.2.1 beta 1, however they unfortunately
did not release any source code files nor a source code patch so far. At
https://download.zarafa.com/community/beta/7.2/7.2.1-49597/ the "sourcecode"
directory is missing.
