Even a "pure-java browser" would rest on the top of a huge pile of native
code (OS, JRE, native libraries). A seemingly innocent piece of data
passed to that native code might trigger a bug (perhaps even a buffer
overflow) in it...
Unlikely (read: less likely than a direct attack vector) but still
possible.
Pavel is talking about native code, which the JVM needs to interface
to the rest of the OS. Native code can have buffer overflows, and
those bugs can be exploitable.
For example:

The risk is several orders of magnitude less, but it is there.
