CVE-2026-43209

CVE-2026-43209 – minix filesystem sanity check in Linux kernel : The minix filesystem implementation lacked proper sanity checks in minix_check_superblock(), notably for s_log_zone_size, which the patch now enforces (only 0 is supported). The update also adds sanity checks for other superblock fi...

CRLF Injection

Overview Affected versions of this package are vulnerable to CRLF Injection via the handling of raw string arguments in commands such as uidsearch, search, uidfetch, fetch, uidstore, store, and setquota. A user can execute arbitrary IMAP commands by injecting specially crafted input containing CR...

net-imap vulnerable to command Injection via "raw" arguments to multiple commands

Summary Several Net::IMAP commands accept a raw string argument that is sent to the server without validation or escaping. If this string is derived from user-controlled input, it may contain contain CRLF sequences, which an attacker can use to inject arbitrary IMAP commands. Details Net::IMAP's...

GHSA-75XQ-5H9V-W6PX net-imap vulnerable to command Injection via unvalidated Symbol inputs

Summary Symbol arguments to commands are vulnerable to a CRLF Injection / IMAP Command injection via Symbol arguments passed to IMAP commands. Details Symbol arguments represent IMAP "system flags", which are formatted as "atoms" with no quoting with a "" prefix. Vulnerable versions of Net::IMAP...

CRLF Injection

Overview Affected versions of this package are vulnerable to CRLF Injection via unvalidated flag arguments in IMAP commands. A user can execute arbitrary IMAP commands by injecting CRLF sequences through crafted Symbol inputs. Remediation Upgrade net-imap to version 0.4.24, 0.5.14, 0.6.4 or highe...

GHSA-87PF-FPWV-P7M7 net-imap vulnerable to denial of service via high iteration count for `SCRAM-*` authentication

Summary When authenticating a connection with SCRAM-SHA1 or SCRAM-SHA256, a hostile server can perform a computational denial-of-service attack on the client process by sending a big iteration count value. Details A hostile IMAP server can send an arbitrarily large PBKDF2 iteration count in the...

Use of Blocking Code in Single-threaded, Non-blocking Context

Overview Affected versions of this package are vulnerable to Use of Blocking Code in Single-threaded, Non-blocking Context through the OpenSSL::KDF.pbkdf2hmac function during SCRAM authentication. An attacker can cause the Ruby client VM to become unresponsive by sending a large iteration count...
