IMAP Library Man-in-the-Middle
The vulnerability in the client API library for the IMAP protocol, written in Ruby, relates to insufficient checking of unusual or exceptional states. Exploiting this vulnerability could allow a malicious actor to carry out a “man-in-the-middle” attack...
UBUNTU-CVE-2026-84641
A malicious IMAP server can trigger use-after-free and heap-memory disclosure by sending a crafted ID response. Heap contents can ultimately be persisted to prefs.js. This vulnerability was fixed in Thunderbird 155, Thunderbird 140.15, and Thunderbird 153.2...
UBUNTU-CVE-2026-42391
An unauthenticated attacker can send an IMAP ID command with a very large number of parameters before logging in, which causes memory and CPU usage to grow disproportionately. The login process can be terminated by the out-of-memory handling, which also terminates all other connections handled by...
net-imap: rubygem-net-imap: Net::IMAP: Denial of Service via malformed command input
A flaw was found in Net::IMAP, a Ruby client library for the Internet Message Access Protocol IMAP. This vulnerability allows a remote attacker to cause a denial of service by sending specially crafted input to certain Net::IMAP commands. When a raw string argument, derived from user-controlled...
net-imap: ruby: Net::IMAP: Information disclosure via man-in-the-middle attack bypassing TLS
A flaw was found in the Ruby net-imap library. When upgrading a cleartext IMAP connection to TLS using the Net::IMAPstarttls method, the library improperly handles certain responses received during STARTTLS negotiation. A man-in-the-middle MITM attacker can inject a predicted tagged OK response...
ruby: net-imap: Net::IMAP: Denial of Service via crafted IMAP responses
A flaw was found in Net::IMAP, a Ruby library implementing the Internet Message Access Protocol IMAP client functionality. A hostile server can exploit a quadratic time complexity issue in the Net::IMAP::ResponseReader when processing large responses containing numerous string literals. This can...
cpython: IMAP command injection in user-controlled commands
A flaw was found in the imaplib module in the Python standard library. The imaplib module does not reject control characters, such as newlines, in user-controlled input passed to IMAP commands. This issue allows an attacker to inject additional commands to be executed in the IMAP server...

AZL-6861 CVE-2021-32066 affecting package ruby for versions less than 2.7.4-1
An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. Net::IMAP does not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between th...
