In GNU Mailman before 2.1.36, the CSRF token for the Cgi/admindb.py admindb page contains an encrypted version of the list admin password. This could potentially be cracked by a moderator via an offline brute-force attack.

An issue was discovered in GNU Hurd before 0.9 20210404-9. When trying to exec a setuid executable, there's a window of time when the process already has the new privileges, but still refers to the old task and is accessible through the old process port. This can be exploited to get full root access.

An issue was discovered in GNU Hurd before 0.9 20210404-9. libports accepts fake notification messages from any client on any port, which can lead to port use-after-free. This can be exploited for local privilege escalation to get full root access.

An issue was discovered in GNU Hurd before 0.9 20210404-9. A single pager port is shared among everyone who mmaps a file, allowing anyone to modify any files that they can read. This can be trivially exploited to get full root access.

In iconvdata/iso-2022-jp-3.c in the GNU C Library (aka glibc) 2.34, remote attackers can force iconv() to emit a spurious '\0' character via crafted ISO-2022-JP-3 data that is accompanied by an internal state reset. This may affect data integrity in certain iconv() use cases. NOTE: the vendor states "the bug cannot be invoked through user input and requires iconv to be invoked with a NULL inbuf, which ought to require a separate application bug to do so unintentionally. Hence there's no security impact to the bug.

GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A certain csrf_token value is derived from the admin password, and may be useful in conducting a brute-force attack against that password.

GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrf_token value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account, and then use that value in a CSRF attack against an admin (e.g., for account takeover).
