According to a report published towards the end of last year by security company MWR Labs, a large number of the SDK’s used by advertising networks are vulnerable to exploitation.
We have analysed a large number of advertising network SDK’s and found that a lot of these implement bridges that are vulnerable to exploitation. Some advertising network SDK’s obtained from the advertising networks directly were found to not be vulnerable (in their most recent versions). However a lot of applications on the 'Google Play Store' were found to be using old versions of the SDK’s, which are vulnerable.
It would be interesting to see a similar analysis for Google Glass.
