CVE-2019-9192
LowSummary
W bibliotece GNU C (glibc lub libc6) do wersji 2.29 występuje niekontrolowana rekurencja w funkcji check_dst_limits_calc_pos_1 w pliku posix/regexec.c, co zostało zademonstrowane przez wyrażenie '(|)(\1\1)*' w narzędziu grep. Utrzymujący oprogramowanie kwestionują, czy jest to rzeczywiście podatność.
Risk Assessment
Organizacje mogą być narażone na ataki, które wykorzystują tę niekontrolowaną rekurencję, co może prowadzić do awarii aplikacji lub systemu. Potencjalne skutki obejmują zwiększone obciążenie zasobów i możliwość odmowy usługi.
Recommendation
Zaleca się aktualizację biblioteki glibc do najnowszej wersji, aby zminimalizować ryzyko związane z tą podatnością. Należy również monitorować aplikacje korzystające z tej biblioteki pod kątem nietypowego zachowania.

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.
