Description Martin Prpič 2015-11-24 13:18:52 UTC 
A flaw was fixed in perl-IPTables-Parse:

(Miloslav Trmač) Fixed a vulnerability to not use predictable names for temporary files. This vulnerability would allow an attacker on a multi- user system to set up symlinks to overwrite any file the current user has write access to. If a user manually overrides the temporary file locations with the 'iptout' and 'ipterr' hash keys, it is recommended to not use predictable names either.
