python: Python base64: Incomplete data decoding due to premature stop at padding

A flaw was found in the Python base64 module. When decoding base64 data using functions like base64.b64decode, the decoding process prematurely stops upon encountering the first padding character. This can result in incomplete data being processed, where any information following the initial...

cpython: cpython: `tarfile` module misinterprets crafted tar archives leading to data integrity issues

A flaw was found in the tarfile module of cpython. This vulnerability allows a remote attacker to craft a malicious tar archive that, when processed, could be misinterpreted by the tarfile module. This misinterpretation occurs because the module incorrectly applies normalization of AREGTYPE block...

python: Quadratic complexity in os.path.expandvars() with user-controlled template

A vulnerability in Python’s os.path.expandvars function that can cause performance degradation. When processing specially crafted, user-controlled input with nested environment variable patterns, the function exhibits quadratic time complexity, potentially leading to excessive CPU usage and denia...

cpython: python: Python zipfile End of Central Directory (EOCD) Locator record offset not checked

A zip file handling flaw has been discovered in the python standard library zipfile module. The 'zipfile' module would not check the validity of the ZIP64 End of Central Directory EOCD Locator record offset value would not be used to locate the ZIP64 EOCD record, instead the ZIP64 EOCD record wou...

cpython: Excessive read buffering DoS in http.client

A flaw was found in the http.client module in the Python standard library. When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This issue allows a malicious server to cause the client to read large amounts of data into...
