Regular Expression Denial of Service (ReDoS) in cross-spawn
Versions of the package cross-spawn before 7.0.5 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU usage and crash the program by crafting a very large and well crafted string.
Tmp files readable by other users in sync-exec
Affected versions of sync-exec
use files located in /tmp/
to buffer command results before returning values. As /tmp/
is almost always set with world readable permissions, this may allow low privilege users on the system to read the results of commands run via sync-exec
under a higher privilege user.
There is currently no direct patch for sync-exec
, as the child_process.execSync
function provided in Node.js v0.12.0 and later provides the same functionality natively.
The best mitigation currently is to update to Node.js v0.12.0 or later, and migrate all uses of sync-exec
to child_process.execSync()
.
