Findings Implications

A majority (24 out of 46) of the concurrency attacks corrupt

pointer data.

Existing memory safety tools, once made aware of concur-

rency, may be able to prevent concurrency attacks that cor-

rupt pointer data.

9 concurrency attacks directly corrupt scalar data, such as

user identifiers, without compromising memory safety.

Few existing defenses handle attacks that directly corrupt

scalar data.

Many existing defenses become unsafe in the face of concur-

rency errors

These defenses must consider concurrent execution.

The exploitability of a concurrency error highly depends on

the duration of its vulnerable window (i.e., the timing win-

dow within which the concurrency error may occur).

New defense techniques may reduce the exploitability of

concurrency errors by reducing the duration of the vulner-

able window.
