To be perfectly honest, there are over thirty thousand different types of spiders and its almost impossible to identify the exact spider you are looking for. I did a little research and one spider I have found is called a Sow Bug Killer its abdomen or rear section, is shaped like a peanut.
There are a couple of different species of spiders with yellow bodies and red legs. The female brown recluse spider and the orb-weaver spider both have these characteristics. It could also be the garden spider or a crab spider. There are over 3500 different species of spider, so it's hard to tell just from the colors what kind it is.
it could be any of these wolf spider, brown recluse, recluse spider,
red spider, mite wolf spider, Most spiders have poision gland but not are all poisionous
It could be a species of orb-weaver spider, which is a common garden spider that is often brightly colored. They're most known for making beautiful spiral webs.
