https://bugzilla.suse.com/show_bug.cgi?id=1224385 Bug ID: 1224385 Summary: VUL-0: CVE-2024-4068: xpra-html5: the npm package `micromatch` is vulnerable to Regular Expression Denial of Service (ReDoS) Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.6 Hardware: Other URL: https://smash.suse.de/issue/405384/ OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Security Assignee: scott.bradnick@suse.com Reporter: smash_bz@suse.de QA Contact: security-team@suse.de CC: gabriele.sonnu@suse.com Target Milestone: --- Found By: Security Response Team Blocker: --- 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. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching.
