Debian Security Advisory 5530-1

Ubuntu Security Notice 7036-1 - It was discovered that Rack was not properly parsing data when processing multipart POST requests. If a user or automated system were tricked into sending a specially crafted multipart POST request to an application using Rack, a remote attacker could possibly use this issue to cause a denial of service. It was discovered that Rack was not properly escaping untrusted data when performing logging operations, which could cause shell escaped sequences to be written to a terminal. If a user or automated system were tricked into sending a specially crafted request to an application using Rack, a remote attacker could possibly use this issue to execute arbitrary code in the machine running the application.

Ubuntu Security Notice 6905-1 - It was discovered that Rack incorrectly handled certain regular expressions. A remote attacker could possibly use this issue to cause Rack to consume resources, leading to a denial of service. It was discovered that Rack incorrectly handled Multipart MIME parsing. A remote attacker could possibly use this issue to cause Rack to consume resources, leading to a denial of service. This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.

There is a possible denial of service vulnerability in the multipart parsing component of Rack. This vulnerability has been assigned the CVE identifier CVE-2022-30122. Versions Affected: >= 1.2 Not affected: < 1.2 Fixed Versions: 2.0.9.1, 2.1.4.1, 2.2.3.1 ## Impact Carefully crafted multipart POST requests can cause Rack's multipart parser to take much longer than expected, leading to a possible denial of service vulnerability. Impacted code will use Rack's multipart parser to parse multipart posts. This includes directly using the multipart parser like this: ``` params = Rack::Multipart.parse_multipart(env) ``` But it also includes reading POST data from a Rack request object like this: ``` p request.POST # read POST data p request.params # reads both query params and POST data ``` All users running an affected release should either upgrade or use one of the workarounds immediately. ## Workarounds There are no feasible workarounds for this issue.

There is a possible shell escape sequence injection vulnerability in the Lint and CommonLogger components of Rack. This vulnerability has been assigned the CVE identifier CVE-2022-30123. Versions Affected: All. Not affected: None Fixed Versions: 2.0.9.1, 2.1.4.1, 2.2.3.1 ## Impact Carefully crafted requests can cause shell escape sequences to be written to the terminal via Rack's Lint middleware and CommonLogger middleware. These escape sequences can be leveraged to possibly execute commands in the victim's terminal. Impacted applications will have either of these middleware installed, and vulnerable apps may have something like this: ``` use Rack::Lint ``` Or ``` use Rack::CommonLogger ``` All users running an affected release should either upgrade or use one of the workarounds immediately. ## Workarounds Remove these middleware from your application
