CVE-2022-0563
LowSummary
Wykryto lukę w narzędziach chfn i chsh z pakietu util-linux, gdy są skompilowane z obsługą Readline. Biblioteka Readline wykorzystuje zmienną środowiskową 'INPUTRC' do uzyskania ścieżki do pliku konfiguracyjnego biblioteki, a w przypadku błędu parsowania pliku, wyświetla komunikat zawierający dane z tego pliku.
Risk Assessment
Luka ta może prowadzić do ujawnienia wrażliwych informacji, co stanowi zagrożenie dla bezpieczeństwa systemu. Atakujący mogą wykorzystać tę podatność do uzyskania dostępu do poufnych danych.
Recommendation
Zaleca się aktualizację pakietu util-linux do najnowszej wersji, aby usunąć tę lukę. Należy również monitorować zmienną środowiskową 'INPUTRC' i jej zawartość.

Hazelcast prior to 5.4.5, 5.5.10, and 5.6.1 contains improper validation of data supplied by a malicious client able to connect to a cluster, allowing arbitrary reads from a cluster member's Java heap, off-heap data, and JVM process address space. The same flaw can crash cluster members and, in some Hazelcast Enterprise Edition configurations, corrupt memory with possible arbitrary code execution. This issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0.
- CVE-2026-107722Critical
fast-jwt from 6.2.0 until 6.3.0 can misclassify RSA public-key text as an HMAC secret when the key has non-whitespace content before its PEM header. In src/crypto.js, performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatcher remains start-anchored, so comments, control characters, zero-width characters, or wrapper text can prevent PEM detection and reach the HMAC fallback. An attacker who knows the public key bytes can sign arbitrary HS256 claims with that public material when HS256 is inferred or allowed, resulting in authentication or authorization bypass. An asymmetric-only algorithm allowlist prevents the attack. This issue is fixed in version 6.3.0.
Original NVD description (English source)
A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the
