Relevant:

"Symantec was prepared for the code to be posted at some point and has developed and distributed a series of patches since Jan. 23rd to protect pcAnywhere users against known vulnerabilities." [1]

If I am understanding this correctly, there were existing and known vulnerabilities that are being patched now because the source was published?

It looks like open source does make software more secure :)
