Vulnerability Details

urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP "Content-Encoding" header (e.g., "gzip", "deflate", "br", or "zstd"). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting "preload_content=False" when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when "preload_content=False". If upgrading is not immediately possible, disable redirects by setting "redirect=False" for requests to untrusted source.

Vulnerability Details

urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.0 and prior to 2.6.0, the Streaming API improperly handles highly compressed data. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header (e.g., gzip, deflate, br, or zstd). The library must read compressed data from the network and decompress it until the requested chunk size is met. Any resulting decompressed data that exceeds the requested amount is held in an internal buffer for the next read operation. The decompression logic could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This can result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data.

Vulnerability Details

urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage and massive memory allocation for the decompressed data. This vulnerability is fixed in 2.6.0.

Vulnerability Details

Requests is a HTTP library. Prior to version 2.33.0, the function "requests.utils.extract_zipped_paths()" (which is used by "HTTPAdapter.cert_verify()" to load the CA bundle, often from the "certifi" package's zipapp structure) uses a predictable, non-unique filename (the basename of the file, e.g., "cacert.pem") when attempting to extract files into the system's temporary directory ("/tmp"). The vulnerable logic performs a check to see if the target file already exists in "/tmp" and re-uses the existing file if found, instead of securely checking the file's content or ensuring atomic, unique extraction. This allows a Local Attacker to pre-create a malicious CA bundle file (e.g., "/tmp/cacert.pem") before a vulnerable application (running with potentially higher privileges) initializes the "requests" library. Version 2.33.0 contains a patch.
