Welcome to Depfu 👋

This is one of the first three pull requests with dependency updates we've sent your way. We tried to start with a few easy patch-level updates. Hopefully your tests will pass and you can merge this pull request without too much risk. This should give you an idea how Depfu works in general.

After you merge your first pull request, we'll send you a few more. We'll never open more than seven PRs at the same time so you're not getting overwhelmed with updates.

Security Advisories 🚨

🚨 Directory Traversal in rubyzip

rubyzip version 1.2.1 and earlier contains a Directory Traversal vulnerability
in Zip::File component that can result in write arbitrary files to the filesystem.
If a site allows uploading of .zip files, an attacker can upload a malicious file
which contains symlinks or files with absolute pathnames "../" to write arbitrary
files to the filesystem.

🚨 Directory traversal vulnerability in rubyzip

The Zip::File component in the rubyzip gem before 1.2.1 for Ruby has a directory
traversal vulnerability. If a site allows uploading of .zip files, an attacker
can upload a malicious file that uses "../" pathname substrings to write arbitrary
files to the filesystem.

Release Notes

1.2.4

• Do not rewrite zip files opened with open_buffer that have not changed #360

Since the GitHub release information for 1.2.2 is missing, I will also include it here:
