The socket placed in /tmp is predictable and public-writable. Therefore if one user placed a symlink to another socket instead of socket for another user then said another user will either be unable to use pcmanfm, or may send requests to the first user's pcmanfm. This bug has been assigned to CVE-2017-8934 [1]. A fix has been committed to pcmanfm's git repository [2]. LXDE developers are working on a release which fixes the problem. [1]: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8934 [2]: https://git.lxde.org/gitweb/?p=lxde/pcmanfm.git;a=commitdiff;h=bc8c3d871e9ecc67c47ff002b68cf049793faf08
The "fix" is ifdef'd for glib >= 2.28.0, so the vulnerability still exists when compiling against an older version of glib. -- Guido Berhoerster
