CVE-2024-4068 – Memory Exhaustion in braces
https://notcve.org/view.php?id=CVE-2024-4068
The NPM package `braces`, versions prior to 3.0.3, 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. El paquete NPM "braces" no limita la cantidad de caracteres que puede manejar, lo que podría provocar agotamiento de la memoria. En `lib/parse.js`, si un usuario malintencionado envía "imbalanced braces" como entrada, el análisis entrará en un bucle, lo que hará que el programa comience a asignar memoria de montón sin liberarla en ningún momento del bucle. • https://devhub.checkmarx.com/cve-details/CVE-2024-4068 https://github.com/micromatch/braces/commit/415d660c3002d1ab7e63dbf490c9851da80596ff https://github.com/micromatch/braces/issues/35 https://github.com/micromatch/braces/pull/37 https://github.com/micromatch/braces/pull/40 https://access.redhat.com/security/cve/CVE-2024-4068 https://bugzilla.redhat.com/show_bug.cgi?id=2280600 • CWE-400: Uncontrolled Resource Consumption CWE-1050: Excessive Platform Resource Consumption within a Loop •
CVE-2024-4067 – Regular Expression Denial of Service in micromatch
https://notcve.org/view.php?id=CVE-2024-4067
The NPM package `micromatch` is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in `micromatch.braces()` in `index.js` because the pattern `.*` will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persists. • https://devhub.checkmarx.com/cve-details/CVE-2024-4067 https://github.com/micromatch/micromatch/blob/2c56a8604b68c1099e7bc0f807ce0865a339747a/index.js#L448 https://github.com/micromatch/micromatch/issues/243 https://github.com/micromatch/micromatch/pull/247 https://github.com/micromatch/micromatch/pull/266 https://github.com/micromatch/micromatch/commit/03aa8052171e878897eee5d7bb2ae0ae83ec2ade https://github.com/micromatch/micromatch/releases/tag/4.0.8 https://advisory.checkmarx.net/advisory/CVE-2024-4067 https:/ • CWE-1333: Inefficient Regular Expression Complexity •
