CVE-2026-101307

When the PCM sample array needs to grow, the RACK stack doubles a 16-bit allocation counter. Repeated doublings caused the counter to wrap to zero, resulting in a near-zero-length allocation followed by a copy of the existing samples into the undersized buffer. A remote peer can trigger the...

Astra Linux – Vulnerability in Ruby-Rack

A denial-of-service vulnerability in the multipart parsing component of Rack was fixed in versions 2.0.9.2, 2.1.4.2, 2.2.4.1, and 3.0.0.1. This vulnerability could allow attackers to craft input that causes the RFC2183 multipart boundary parsing in Rack to take an unexpectedly long time,...

Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. Prior to versions 2.2.14, 3.0.16, and 3.1.14, Rack::QueryParser parsed query strings and application/x-www-form-urlencoded bodies into Ruby data structures without imposing any limit on the number of parameters. This allowed attackers to send requests...

Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Static used a simple string prefix check to determine whether a request should be served as a static file. When configured with URL prefixes like "/css", it matched any request path that began with tha...

Astra Linux – Vulnerability in 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 could accumulate unbounded data when the header block of a multipart part never ended with the required blank line CRLFCRLF. The parser continuously stored incoming bytes in memory...
