Description SMASH SMASH 2024-05-16 11:57:20 UTC

The NPM package `braces` fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. In `lib/parse.js,` if a malicious user sends "imbalanced braces" as input, the parsing will enter a loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash.

Comment 1 Gabriele Sonnu 2024-05-16 12:04:10 UTC

A vulnerable version (3.0.2) of the braces package is embedded in:

- openSUSE:Factory/python-pytest-html

Upstream issue:

Comment 2 Daniel Garcia 2024-05-20 08:10:57 UTC

python-pytest-html braces dependency is as follow:

 1. mocha -> chokidar -> braces
 2. sass -> chokidar -> braces

1. mocha is used for tests, that we don't run, so can be removed, or even ignored. In any case there's an issue in chokidar about this and looks like the score is too high: https://github.com/paulmillr/chokidar/issues/1314
2. sass is not vulnerable: https://github.com/sass/dart-sass/issues/2243

So after this small analysis we can say that this package is not affected.

Comment 3 Daniel Garcia 2024-05-21 08:23:15 UTC

Looks like there's a fix in braces upstream [1] to avoid this issue. There will be a new release soon.

We can close this, then.
