rack: Rack memory exhaustion denial of service

A denial of service flaw has been found in the rubygems rack package. Rack::Multipart::Parser can accumulate unbounded data when a multipart part’s header block never terminates with the required blank line CRLFCRLF. The parser keeps appending incoming bytes to memory without a size cap, allowing...

rack: Rack's unbounded multipart preamble buffering enables DoS (memory exhaustion)

A flaw was found in Rack where the Rack::Multipart::Parser buffers the multipart preamble memory without size limits. A remote attacker can send a crafted multipart/form-data request with a very large preamble before its first boundary, causing excessive memory consumption and denial of service...

CVE-2025-58183

A flaw was found in the archive/tar package in the Go standard library. tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A specially crafted tar archive with a pax header indicating a big number of sparse regions can cause a Go...
