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...
Important: Red Hat Security Advisory: pcs security update
An update for pcs is now available for Red Hat Enterprise Linux 10. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the...
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...
rubygem-rack: Rack QueryParser has an unsafe default allowing params_limit bypass via semicolon-separated parameters
An unsafe default behavior in Rack::QueryParser allows bypass of the paramslimit parameter count restriction when query string parameters are delimited by semicolons ; rather than ampersands &. The parser counts only & when enforcing the limit, while still splitting on both & and ;. As a result, ...
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...

rubygem-rack: Unbounded read in `Rack::Request` form parsing can lead to memory exhaustion
A memory-exhaustion vulnerability exists in Rack when parsing application/x-www-form-urlencoded request bodies. Rack::RequestPOST reads the entire request body into memory without enforcing a maximum length or cap. Attackers can exploit this by sending large form submissions, potentially causing...

Denial-of-Service (DoS)
rack is vulnerable to Denial-Of-Service. The vulnerability is due to Rack::RequestPOST reading the entire application/x-www-form-urlencoded body into memory due to calling rack.input.readnil without enforcing a length limit, and attackers can send very large form bodies to exhaust process memory...
Information Disclosure
rack is vulnerable to Information Disclosure. The vulnerability is due to trusting unvalidated x-sendfile-type and x-accel-mapping headers, allowing attackers to craft headers that trick the proxy into making internal requests and bypassing access controls...
Parameter-parsing Bypass
Rack is vulnerable to a parameter-parsing Bypass. The vulnerability is due to Rack::QueryParser enforcing its paramslimit only for parameters separated by & while still splitting on both & and ;, which allows an attacker to bypass the parameter count limit by using ; separators to submit excessiv...
