May 12, 2012 at 8:03 comment added CodesInChaos The second attack on the other hand is very tricky. Especially since a file can have several formats at the same time. For example there is a gif file, that's a jar(java archive) at the same time. The heuristics used by content sniffing are unclear too, making defense pretty hard.
May 12, 2012 at 8:00 comment added CodesInChaos The first attack demonstrates why encoding on output is superior to sanitizing the input. Makes it much harder to miss such a case.
