Affected: ruby net-imap

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.

Affected: Ubuntu:20.04:LTS: ruby2.7, Ubuntu:22.04:LTS: ruby3.0, Ubuntu:24.04:LTS: ruby3.2

It was discovered that Ruby incorrectly handled parsing of an XML document that has specific XML characters in an attribute value using REXML gem. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service. This issue only affected in Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 24.10. (CVE-2024-35176, CVE-2024-39908, CVE-2024-41123, CVE-2024-43398)

It was discovered that Ruby incorrectly handled expanding ranges in the net-imap response parser. If a user or automated system were tricked into connecting to a malicious IMAP server, a remote attacker could possibly use this issue to consume memory, leading to a denial of service. This issue only affected Ubuntu 24.04 LTS, and Ubuntu 24.10. (CVE-2025-25186)

It was discovered that the Ruby CGI gem incorrectly handled parsing certain cookies. A remote attacker could possibly use this issue to consume resources, leading to a denial of service. (CVE-2025-27219)

It was discovered that the Ruby CGI gem incorrectly handled parsing certain regular expressions. A remote attacker could possibly use this issue to consume resources, leading to a denial of service. (CVE-2025-27220)

It was discovered that the Ruby URI gem incorrectly handled certain URI handling methods. A remote attacker could possibly use this issue to leak authentication credentials. (CVE-2025-27221)
