Description Adam Mariš 2015-10-01 13:14:22 UTC

A vulnerability in perl-IPTables-Parse was found, when using predictable file names for its temporary files. This vulnerability allows attacker on a multi-user system to set up symlinks to overwrite any file the current user has write access to.

Note that perl-IPTables-Parse is also used by fwsnort and perl-IPTables-ChainMgr, which is used by psad.
