sympa.pl in sympa 5.3.4 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/sympa_aliases.$$ temporary file. NOTE: wwsympa.fcgi was also reported, but the issue occurred in a dead function, so it is not a vulnerability.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
