Description Vincent Danen 2014-08-29 19:53:05 UTC 
It was reported [1],[2] that the clipedit program as shipped with perl-Clipboard uses temporary files insecurely (based on the PID of the running program).  Using symlink attacks, an attacker could cause the deletion of arbitrary files that the user running clipedit has write access to.

 [...]
  7 my $tmpfilename = "/tmp/clipedit$$";  
  8 open my $tmpfile, ">$tmpfilename" or die "Failure to open $tmpfilename: $!";  
  9 print $tmpfile $orig;  
 10 close $tmpfile;
 [...]
 13 system($ed, $tmpfilename);  
 14   
 15 open $tmpfile, $tmpfilename or die "Failure to open $tmpfilename: $!";
 16 my $edited = join '', <$tmpfile>;
 [...]
 49 unlink($tmpfilename) or die "Couldn't remove $tmpfilename: $!";
