### Impact Some CORS middleware (more specifically those created by specifying two or more origin patterns whose hosts share a proper suffix) incorrectly allow some untrusted origins, thereby opening the door to cross-origin attacks from the untrusted origins in question. For example, specifying origin patterns `https://foo.com` and `https://bar.com` (in that order) would yield a middleware that would incorrectly allow untrusted origin `https://barfoo.com`. ### Patches Patched in v0.9.0. ### Workarounds None.

### Summary An attacker can send a specially crafted POST (multipart/form-data) request. When the aiohttp server processes it, the server will enter an infinite loop and be unable to process any further requests. ### Impact An attacker can stop the application from serving requests after sending a single request. ------- For anyone needing to patch older versions of aiohttp, the minimum diff needed to resolve the issue is (located in `_read_chunk_from_length()`): ```diff diff --git a/aiohttp/multipart.py b/aiohttp/multipart.py index 227be605c..71fc2654a 100644 --- a/aiohttp/multipart.py +++ b/aiohttp/multipart.py @@ -338,6 +338,8 @@ class BodyPartReader: assert self._length is not None, "Content-Length required for chunked read" chunk_size = min(size, self._length - self._read_bytes) chunk = await self._content.read(chunk_size) + if self._content.at_eof(): + self._at_eof = True return chunk async def _read_chunk_from_stre...

libxmljs2 is vulnerable to type confusion when parsing a specially crafted XML while invoking a function on the result of attrs() that was called on a parsed node. This vulnerability might lead to denial of service (on both 32-bit systems and 64-bit systems), data leak, infinite loop and remote code execution (on 32-bit systems with the XML_PARSE_HUGE flag enabled). At the time of publication, there is no fix.

libxmljs2 is vulnerable to a type confusion vulnerability when parsing a specially crafted XML while invoking the `namespaces()` function (which invokes `XmlNode::get_local_namespaces()`) on a grand-child of a node that refers to an entity. This vulnerability can lead to denial of service and remote code execution.
