Both are released only after THAW returns, so a THAW that dies leaves the whole decoded argument structure allocated.\n\nEach rejected document leaks data of a size the sender chooses, so a process that catches the error and keeps running exhausts its memory.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-401"],"vendors":[],"products":[],"references":[{"url":"https://github.com/rurban/Cpanel-JSON-XS/commit/9ab010221c069a7af9ef7463454ecd3b8ace9c58.patch","tags":[]},{"url":"https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes","tags":[]}],"exploitRefs":[{"url":"https://github.com/rurban/Cpanel-JSON-XS/commit/9ab010221c069a7af9ef7463454ecd3b8ace9c58.patch","tags":[]}],"hasPoc":true,"ai":null}
