CVE-2024-23301 [MEDIUM] CWE-276 CVE-2024-23301: Relax-and-Recover (aka ReaR) through 2.7 creates a world-readable initrd when using GRUB_RESCUE=y. T Relax-and-Recover (aka ReaR) through 2.7 creates a world-readable initrd when using GRUB_RESCUE=y. This allows local attackers to gain access to system secrets otherwise only readable by root.

CVE-2025-46398 [MEDIUM] CWE-121 CVE-2025-46398: In xfig diagramming tool, a stack-overflow while running fig2dev allows memory corruption via local In xfig diagramming tool, a stack-overflow while running fig2dev allows memory corruption via local input manipulation via read_objects function.

CVE-2023-4641 [MEDIUM] CWE-303 CVE-2023-4641: A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twi A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory.

CVE-2026-11819 [MEDIUM] CWE-532 CVE-2026-11819: Module: plugins/modules/keyring_info.py CVSS 3.1: 5.5 MEDIUM — AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N Module: plugins/modules/keyring_info.py CVSS 3.1: 5.5 MEDIUM — AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N Issue: The module retrieves a passphrase from the OS native keyring (GNOME Keyring, macOS Keychain, Windows Credential Manager) and places it directly into result["passphrase"] with no output suppression, no no_log protection, and no documentation warn
