python: Python tarfile module: Denial of Service via improper EOF handling in streaming mode

A flaw was found in the Python tarfile module. When processing a specially crafted tar archive opened in 'streaming mode' mode='r|', the module does not properly handle the end-of-file EOF condition. This can cause the tarfile module to enter an infinite loop, leading to a Denial of Service DoS f...

python: Python: Performance degradation in XML processing due to quadratic time complexity

A flaw was found in Python's xml.etree.ElementPath component. This vulnerability can lead to a denial of service DoS when processing specially crafted XML documents. Specifically, certain XPath index predicates used with functions like Element.findall and Element.iterfind can cause the processing...

python: Python: CPU Denial of Service in HTML parser via repeated unterminated markup declarations

A flaw was found in Python. Its incremental HTML parser can be exploited by a remote attacker. By sending specially crafted, uncontrolled data with repeated, incomplete markup declarations, the attacker can cause the system to consume excessive central processing unit CPU resources. This leads to...

python: cpython: CPython: tarfile extraction filter bypass allows escaping the destination directory

A flaw was found in the tarfile.extractall function within Python. A remote attacker could exploit this vulnerability by providing a specially crafted archive. This archive could bypass security filters by using a hardlink that references a symlink, allowing the symlink to be recreated outside th...

python: Python Tarfile: Unexpected file ownership when extracting hardlinks

A flaw was found in the Python Tarfile.extract function. This vulnerability occurs when processing untrusted tar files containing hardlinks, as the filter parameter is not correctly enforced. An attacker could exploit this to write files with unintended user or group ownership, potentially leadin...
