-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Format: 1.8 Date: Tue, 15 Sep 2026 00:52:10 +0800 Source: redis Architecture: source Version: 5:8.0.2-3+deb13u3 Distribution: trixie-security Urgency: high Maintainer: Chris Lamb <[email protected]> Changed-By: Aron Xu <[email protected]> Closes: 1147421 1147422 1147423 Changes: redis (5:8.0.2-3+deb13u3) trixie-security; urgency=high . * Non-maintainer upload by the Security Team. * CVE-2026-25243: Invalid memory access in RESTORE. The RESTORE command did not properly validate serialized values; an authenticated attacker able to run RESTORE could supply a crafted payload triggering invalid memory access and possibly remote code execution. (Closes: #1147421) * CVE-2026-23631: Lua use-after-free on replicas. An authenticated attacker could exploit the master-replica synchronization mechanism to trigger a use-after-free on replicas where replica-read-only is disabled, potentially leading to remote code execution. (Closes: #1147421) * CVE-2026-23479: Use-after-free in the unblock client flow. The error return from processCommandAndResetClient was not handled when re- executing a blocked command, allowing an authenticated attacker to trigger a use-after-free and possibly remote code execution. (Closes: #1147421) * CVE-2026-66373: Double free via RESTORE of a stream whose NACK is shared by several consumers, an incomplete fix for CVE-2026-25243; deleting both consumers with XGROUP DELCONSUMER could lead to remote code execution. (Closes: #1147422) * CVE-2026-81934: Use-after-free in tlsProcessPendingData() when handling the TLS pending-data list. A remote unauthenticated attacker may be able to execute arbitrary code with the privileges of the server. (Closes: #1147423) * Some important fixes upstream shipped as security fixes without CVE: - From 8.2.9: ACL key-permission bypass in SORT, GEORADIUS/GEORADIUSBYMEMBER and XREAD/XREADGROUP, out-of-bounds argv access during ACL key extraction for wrong-arity KEYNUM commands, out-of-range SLOT_INFO slot id in RDB loading causing memory corruption, and a use-after-free in handleClientsBlockedOnKey when reprocessing a command evicts another client blocked on the same key. - From 8.0.5: out-of-bounds argv read and crash in HGETEX when the FIELDS option lacks its numfields argument, and an integer overflow in the HyperLogLog MurmurHash64A with entries over 2GB.
