This particular source probably isn't surprising as many software companies are expected to disclose their code to foreign governments in order to win business. Oddly, there is a level of distrust that such companies may have installed 'backdoors' at the instigation various US-based "men in low hats."
The surprise is that the government repository was so easily accessed.
Be that as it may, it is reasonable to assume that security software evolves at a relatively high rate, given the rapid evolution of the threats it is intended to deal with. And thus any similarity between the 2006 version and the current version would be cursory at best.
Except, it seems, when it comes to Symantec's remote-access software pcAnywhere.
Effective immediately, Symantec has advised all users of pcAnywhere to stop using the product until an updated version (which is clearly under urgent development) is available.
According to the Symantec announcement:
Malicious users with access to the source code have an increased ability to identify vulnerabilities and build new exploits. Additionally, customers that are not following general security best practices are susceptible to man-in-the-middle attacks which can reveal authentication and session information. General security best practices include endpoint, network, remote access, and physical security, as well as configuring pcAnywhere in a way that minimizes potential risks.
At this time, Symantec recommends disabling the product until Symantec releases a final set of software updates that resolve currently known vulnerability risks. For customers that require pcAnywhere for business critical purposes, it is recommended that customers understand the current risks, ensure pcAnywhere 12.5 is installed, apply all relevant patches as they are released, and follow the general security best practices discussed herein.
One might have hoped that a properly built package would have been immune to source inspection, but it seems not to be true; suggesting that there are connection 'secrets' or other useful information enshrined in there.
With that in mind, perhaps the Indian government was on to something after all.
