On a miss it keeps everything and searches again from the start when the next chunk arrives. A body with no boundary, or with a delimiter followed by neither CRLF nor \"--\", is therefore rescanned on every chunk, taking time quadratic in its size.\n\nA remote attacker can exhaust worker CPU with a few such requests.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-407"],"vendors":[],"products":[],"references":[{"url":"https://github.com/libwww-perl/HTTP-Body/commit/bf77eb959bbe1641b77f69eefe98d58ce4c4ec79.patch","tags":[]},{"url":"https://metacpan.org/release/GETTY/HTTP-Body-1.24/changes","tags":[]}],"exploitRefs":[{"url":"https://github.com/libwww-perl/HTTP-Body/commit/bf77eb959bbe1641b77f69eefe98d58ce4c4ec79.patch","tags":[]}],"hasPoc":true,"ai":null}
