Updated rxvt-unicode packages fix CVE-2014-3121

Updated rxvt-unicode package fixes security vulnerability: rxvt-unicode (aka urxvt) before 9.20 is vulnerable to a user-assisted arbitrary commands execution issue. This can be exploited by the unprocessed display of certain escape sequences in a crafted text file or program output. Arbitrary command sequences can be constructed using this, and unintentionally executed if used in conjunction with various other escape sequences (CVE-2014-3121).
