@RuCTFE. Found the stack overflow, but no leak (collected_pieces was spilled to the stack, so no retaddr LSB overwrite either). Reading short in check_fuel was throwing.https://github.com/HackerDom/ructfe-2019/commit/db4187f50d6bfd4ae7b1a86f336f3028bef6602e# …Thanks. Twitter will use this to make your timeline better.

Played some
#GoogleCTF yesterday on the Chrome pwnable. Wanted to reclaim the UAF being with another being to bump the std::string for leak + AARW (after further corruption), but had trouble with reclaiming due to Mojo temporaries in the same tcmalloc size class. Any insight?Thanks. Twitter will use this to make your timeline better. UndoUndo -
