pip: pip: Incorrect file installation due to improper archive handling

A flaw was found in pip. This vulnerability occurs because pip incorrectly processes concatenated tar and ZIP files as ZIP files, regardless of their true format. This improper handling can lead to confusing installation behavior, potentially causing the installation of unintended or 'incorrect'...

Directory Traversal

Overview decompress is a package that can be used for extracting archives. Affected versions of this package are vulnerable to Directory Traversal and link following during archive extraction, where symlink and hardlink entries are created without checking their targets and the directory...

Decompress: Archive extraction can create files and links outside of the target directory

Impact When extracting an archive to a directory, a crafted archive can read or write files outside that directory. The flaw is in the code that writes the parsed entries, so it affects every format decompress handles: tar, tar.gz, tar.bz2, and zip by default, plus any others added through the...

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...
