Bumps rack from 1.4.1 to 1.4.7. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Potential Denial of Service Vulnerability in Rack
Carefully crafted requests can cause a SystemStackError and potentially
cause a denial of service attack.

All users running an affected release should upgrade.

Patched versions: >= 1.6.2; ~> 1.5.4; ~> 1.4.6
Unaffected versions: none

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects rack
lib/rack/multipart.rb in Rack before 1.1.4, 1.2.x before 1.2.6, 1.3.x before 1.3.7, and 1.4.x before 1.4.2 uses an incorrect regular expression, which allows remote attackers to cause a denial of service (infinite loop) via a crafted Content-Disposion header.

Affected versions: >= 1.4.0, < 1.4.2

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects rack
multipart/parser.rb in Rack 1.3.x before 1.3.8 and 1.4.x before 1.4.3 allows remote attackers to cause a denial of service (memory consumption and out-of-memory error) via a long string in a Multipart HTTP packet.

Affected versions: >= 1.4.0, < 1.4.3

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects rack
rack/file.rb (Rack::File) in Rack 1.5.x before 1.5.2 and 1.4.x before 1.4.5 allows attackers to access arbitrary files outside the intended root directory via a crafted PATH_INFO environment variable, probably a directory traversal vulnerability that is remotely exploitable, aka "symlink path traversals."

Affected versions: >= 1.4.0, < 1.4.5
