Package Instance

Uncontrolled Resource Consumption
lib/rack/multipart.rb in Rack  uses an incorrect regular expression, which allows remote attackers to cause a denial of service (infinite loop) via a crafted Content-Disposion header.

Improper Restriction of Operations within the Bounds of a Memory Buffer
multipart/parser.rb in Rack 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.

XSS exploit of RDoc documentation generated by rdoc
This exploit may lead to cookie disclosure to third parties. The exploit exists in darkfish.js which is copied from the RDoc install location to the generated documentation. RDoc is a static documentation generation tool. Patching the library itself is insufficient to correct this exploit.

Denial of Service and SQL Injection
This package allows remote attackers to cause a denial of service (resource consumption) or bypass the mass assignment protection mechanism via a crafted JSON document that triggers the creation of arbitrary Ruby symbols or certain internal objects, as demonstrated by conducting a SQL injection attack against Ruby on Rails, aka.

Incorrect temporary file usage
The ruby_parser Gem does not create temporary files securely. In the `diff_pp` function contained in `lib/gauntlet_rubyparser.rb` function, it creates files as `/tmp/a.[pid]` and `/tmp/b.[pid]` which can be predicted and used for either a denial of service (file cannot be overwritten), or to change the contents of files that are writable.

Uncontrolled Resource Consumption
Unspecified vulnerability in Rack::Auth::AbstractRequest in Rack  allows remote attackers to cause a denial of service via unknown vectors related to "symbolized arbitrary strings."

Circumvention of attr_protected
The attr_protected method allows developers to specify a denylist of model attributes which users should not be allowed to assign to. By using a specially crafted request, attackers could circumvent this protection and alter values that were meant to be protected.

Timing attack against Rack::Session::Cookie
Affected versions allows remote attackers to guess the session cookie, gain privileges, and execute arbitrary code via a timing attack involving am HMAC comparison function that does not run in constant time.
