Astra Linux - уязвимость в ruby-rack

Rack is a modular Ruby web server interface. In versions prior to 2.2.19, 3.1.17, and 3.2.2, “Rack::Multipart::Parser” stores non-file form fields fields without a filename entirely in memory as Ruby String objects. A single large text field in a multipart/form-data request hundreds of megabytes ...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-005314 advisory. Rack is a modular Ruby web server interface. In versions prior to 2.2.19, 3.1.17, and 3.2.2, Rack::Multipart::Parser stores non-file form fields parts without a...

Denial Of Service (DoS)

rack is vulnerable to Denial Of Service. The vulnerability is due to unbounded in-memory storage of non-file multipart form fields in Rack::Multipart::Parser, where attackers can send extremely large text fields that consume process memory and trigger OOM conditions, leading to DoS...

rack: Rack's multipart parser buffers large non‑file fields entirely in memory, enabling DoS (memory exhaustion)

A flaw was found in Rack where Rack::Multipart::Parser stores non-file form fields entirely in memory without size limits. An attacker can send a multipart/form-data request with an extremely large text field, causing the server to allocate large amounts of memory which leads to a denial of servi...
