There's been plenty of vulnerabilities in email and HTML caused by 
non-active content, primarily overflows due to improper parsing of 
headers and mime boundaries. Microsoft is definitely not the only one 
plagued by those, and their vulnerabilities in email applications has 
mainly been due to their HTML integration and, by extension, IE 
vulnerabilities.

Yes, IE has been a horrendous melting pot of functionality that each 
increased complexity beyond the point where all possible interactions 
could be logically deduced, or even properly fuzzed. Most of the 
traditional IE vulnerabilities outside overflows have been logic flaws 
which are eerily similar to the continuous Chrome flaws in Firefox.

Firefox has an SQLite implementation of their memory and disk browser 
cache that's just waiting to be turned on with a configure option. I've 
already reported SQL injection vulnerabilities in that code which can be 
used for file reading, writing and execution, but it's not going to get 
any attention until just prior to the feature being enabled for the main 
distributions.
