One surprising behavior of TSX, which is essentially the root cause of this security loophole, is that it aborts a transaction without notifying the underlying kernel even when the transaction fails due to a critical error, such as a page fault or an access violation, which traditionally requires kernel intervention. To reliably exploit the side channels, the DrK attack took advantage of Intel TSX (Transactional Synchronization eXtension). Processed chunks are wrapped with SPAN tag, so semantic units will no longer be split at the end of a line by specifying their display property as inline-block in CSS.ĭrK is an attack that breaks kernel address space layout randomization (KASLR) by exploiting TLB and decoded i-cache side channel. Budou uses Google Cloud Natural Language API (NL API) to analyze the input sentence, and it concatenates proper words in order to produce meaningful chunks utilizing part-of-speech (pos) tagging and syntactic information. This is a long standing issue in typography on web, and results in degradation of readability.Budou automatically translates CJK sentences into organized HTML code with lexical chunks wrapped in non-breaking markup so as to semantically control line breaks. Breaks occur randomly, usually in the middle of a word. Certain CJK languages have none of these, and are notoriously more difficult. Budou - Budou is an automatic organizer tool for beautiful line breaking in CJK (Chinese, Japanese, and Korean)Įnglish uses spacing and hyphenation as cues to allow for beautiful and legible line breaks.
