CVE-2025-27219 (GCVE-0-2025-27219)

Vulnerability from cvelistv5 – Published: 2025-03-03 00:00 – Updated: 2025-11-03 21:13

Summary

In the CGI gem before 0.4.2 for Ruby, the CGI::Cookie.parse method in the CGI library contains a potential Denial of Service (DoS) vulnerability. The method does not impose any limit on the length of the raw cookie value it processes. This oversight can lead to excessive resource consumption when parsing extremely large cookies.

Severity ?

5.8 (Medium)

CVE-2025-25186 (GCVE-0-2025-25186)

Vulnerability from cvelistv5 – Published: 2025-02-10 15:55 – Updated: 2025-02-12 15:46

Title

Net::IMAP vulnerable to possible DoS by memory exhaustion

Summary

Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Starting in version 0.3.2 and prior to versions 0.3.8, 0.4.19, and 0.5.6, there is a possibility for denial of service by memory exhaustion in `net-imap`'s response parser. At any time while the client is connected, a malicious server can send can send highly compressed `uid-set` data which is automatically read by the client's receiver thread. The response parser uses `Range#to_a` to convert the `uid-set` data into arrays of integers, with no limitation on the expanded size of the ranges. Versions 0.3.8, 0.4.19, 0.5.6, and higher fix this issue. Additional details for proper configuration of fixed versions and backward compatibility are available in the GitHub Security Advisory.

CVE-2025-27221 (GCVE-0-2025-27221)

Vulnerability from cvelistv5 – Published: 2025-03-03 00:00 – Updated: 2025-11-03 21:13

Summary

In the URI gem before 1.0.3 for Ruby, the URI handling methods (URI.join, URI#merge, URI#+) have an inadvertent leakage of authentication credentials because userinfo is retained even after changing the host.

Severity ?
