A new binary software randomization and ControlFlow Integrity (CFI) enforcement system is presented, which is the first to efficiently resist code-reuse attacks launched by informed adversaries who possess full knowledge of the inmemory code layout of victim programs. The defense mitigates a recent wave of implementation disclosure attacks, by which adversaries can exfiltrate in-memory code det...

BACKGROUND Thus far, it is unknown whether there is functional collateral flow through preexisting anastomoses in patients with angiographically normal coronary arteries. Such preformed coronary collateral vessels could form the basis for subsequently developing protective natural bypasses in the presence of coronary artery disease. METHODS AND RESULTS Among 100 patients, the collateral flow ...

Three isolates of feline calicivirus (FCV) designated NADC, KCD and CFI/68 were compared for biochemical, serological and genetic variation within the capsid protein gene. The M(r) of the capsid protein from purified virions was approximately 66,000 for the NADC virus isolate, which differed slightly from the relative mobilities of the purified capsid proteins of the KCD and CFI/68 isolates. Po...

We propose and evaluate a new protection mechanism for indirect call and jump instructions in binaries, which we call FPGate. FPGate stops attacks targeting function pointers by limiting indirect transfers to only those targets that are legal in the original program. When deployed together with other existing lightweight protections, FPGate can provide a level of protection comparable to CFI (C...

Intracoronary Growth Factor Concentrations in Patients With 1to 3-Vessel Coronary Artery Disease To the Editor: We enjoyed reading the article by Fleisch et al1 but would like to point out a number of potential factors that detract from the data reported. In particular, we are concerned about the measurement of growth factors and collateral flow index (CFI). As the authors acknowledge, both vas...

Control Flow Integrity (CFI) is a computer security technique that detects runtime attacks by monitoring a program’s branching behavior. This work presents a detailed analysis of the security policies enforced by 21 recent hardware-based CFI architectures. The goal is to evaluate the security, limitations, hardware cost, performance, and practicality of using these policies. We show that many a...

This manual describes version 1.0 of the Monte Carlo event generator KROWIG for deep inelastic lepton hadron scattering at HERA. KROWIG combines the implementation of QED radiative corrections in KRONOS with the QCD parton showers and cluster fragmentation of HERWIG.
