Attackers can supply JavaScript that enlarges a dense array's length and calls sort, causing Ap_sort_cmp and Ap_sort_swap to access slots past the buffer and crash the process.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://codeberg.org/ccxvii/mujs","tags":[]},{"url":"https://codeberg.org/ccxvii/mujs/commit/32064e10caa45e68fc87331ca53d042049cc9396","tags":[]},{"url":"https://codeberg.org/ccxvii/mujs/src/commit/307f18c4216420f2f56e22d8e7040baa39a6304a/jsarray.c#L245","tags":[]},{"url":"https://hackmd.io/@haind-pwn/mujs-array-length-flat-oob","tags":[]},{"url":"https://mujs.com/downloads/","tags":[]},{"url":"https://www.vulncheck.com/advisories/mujs-1.3.6-before-1.3.9-heap-out-of-bounds-read-write-via-array-prototype-sort","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
