python: Python: Information disclosure due to incorrect URL scheme matching

A flaw was found in Python. The HTTPPasswordMgr class in the urllib.request module did not correctly consider the URL scheme when matching stored credentials against a requested URL. This allowed credentials intended for an HTTPS secure connection to be sent over an unencrypted HTTP connection to...

python: Python stringprep module: Incorrect domain name processing breaks IDNA interoperability

A flaw was found in the Python 'stringprep' module. This module incorrectly processed characters by using the latest Unicode codepoint attributes instead of the Unicode 3.2.0 standard specified in RFC 3454. This deviation can lead to mismatches when processing internationalized domain names IDNA...

python: Python tarfile module: Directory traversal allows creation of empty directories outside extraction destination

A flaw was found in the Python tarfile module. This vulnerability allows an attacker to create empty directories outside of the intended extraction destination on POSIX Portable Operating System Interface platforms. This occurs when processing a specially crafted archive containing member names...

python: Python: Denial of Service via crafted zip file memory pre-allocation

A flaw was found in Python. When decompressing specially crafted zip files that use bzip, LZMA, or Zstandard compression methods, Python may pre-allocate memory based on an attacker-controlled size. This could lead to excessive memory consumption, potentially causing a Denial of Service DoS for t...
