CVE-2024-26461
LowSummary
Kerberos 5 w wersji 1.21.2 zawiera podatność na wyciek pamięci w pliku /krb5/src/lib/gssapi/krb5/k5sealv3.c. Problem ten może prowadzić do nieefektywnego zarządzania pamięcią w aplikacjach korzystających z tej biblioteki.
Risk Assessment
Wyciek pamięci może prowadzić do zwiększonego zużycia zasobów systemowych, co w dłuższej perspektywie może wpłynąć na stabilność i wydajność systemu. Organizacje mogą być narażone na ataki, które wykorzystują tę podatność do destabilizacji usług.
Recommendation
Zaleca się aktualizację Kerberos 5 do najnowszej wersji, aby usunąć tę podatność. Należy również monitorować aplikacje korzystające z tej biblioteki pod kątem nieprawidłowego działania.

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.
