The cli package, a tool designed for quick command-line application development, saw a minor version update from 0.4.1 to 0.4.2 in April 2012. Both versions share the same core purpose: streamlining the creation of command-line interfaces. They also list glob (version 3.1.4 or higher) as a dependency, suggesting utility for file system path matching, a common requirement in CLI tools. Examining the metadata reveals a relatively small gap between releases, with version 0.4.2 arriving less than two months after 0.4.1. This implies the update likely contains bug fixes, minor enhancements, or small feature additions rather than a total rewrite or a major overhaul.
While a deeper analysis (e.g., commit logs) is needed to pinpoint the exact changes, developers considering incorporating cli should weigh the benefits of using potentially more stable albeit older version 0.4.1 as opposed to the presumably improved version 0.4.2. It's advisable to check code repositories or changelogs for a detailed understanding of included fixes or new added functionalities in version 0.4.2 which might justify the update, particularly if the CLI app relies on path matching via glob or experienced specific issues previously. Also, developers should be mindful of the age of both versions, as modern CLI development might benefit from newer, actively maintained packages with richer feature sets.

Arbitrary File Write in cli
Affected versions of cli use predictable temporary file names. If an attacker can create a symbolic link at the location of one of these temporarly file names, the attacker can arbitrarily write to any file that the user which owns the cli process has permission to write to.
By creating Symbolic Links at the following locations, the target of the link can be written to.
lock_file = '/tmp/' + cli.app + '.pid',
log_file = '/tmp/' + cli.app + '.log';
Update to version 1.0.0 or later.
