high Nessus Plugin ID 376351

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-1fd9c58e29 advisory.

## Valkey 8.1.11 - Released Mon 26 October 2026

Upgrade urgency SECURITY: This release includes security fixes we recommend you apply as soon as possible.

### Security Fixes
* GHSA-f4q9-j22m-xqq9: Fix a heap buffer overflow in cluster Pub/Sub message construction that could allow an authenticated client to potentially execute arbitrary code by publishing an oversized message by @roshkhatri (#5030)

### Bug Fixes
* Fix stream commands that mutate consumer-group or PEL state (`XGROUP`, `XSETID`, `XREADGROUP`, `XACK`, `XCLAIM`, `XAUTOCLAIM`) not triggering `WATCH` and client-side tracking invalidation by @Tarte12 (#3459)
* Fix a server crash when module timer callbacks or thread-safe contexts attempt writes while writes are paused by `CLIENT PAUSE WRITE` or `CLUSTER FAILOVER`; such module writes are now rejected by @smkher (#3645)
* Fix a server abort on a RESTORE payload declaring a string length that overflows the allocation size;
such payloads are now rejected as bad data by @enjoy-binbin (#4733)
* Fix ZINTER/ZINTERSTORE returning input-order-dependent scores when a weighted term is 0*inf; a NaN weighted score now counts as 0, matching ZUNION by @leomurillo (#4997)
* Correct `ValkeyModule_FreeModuleUser`, `ValkeyModule_ACLAddLogEntry` and `ValkeyModule_ACLAddLogEntryByUserName` declarations to return int as implemented, fixing undefined behavior on targets with strict call signature checks by @rainsupreme (#4676)
* Fix a huge memory allocation when a command such as COMMAND GETKEYS EVAL declares a far larger key count than the arguments provided by @murphyjacob4 (#3598)
* Reject relative expire times in `SET`/`GETEX`, `RESTORE`, and the module `SetExpire` API that overflow when the current time is added, preventing negative expires that abort the server by @madolson (#4880)
* Fix a server crash when loading an ACL file containing a selector with an unmatched parenthesis by @magic-peach (#4214)
* Fix sorted set range commands with a negative LIMIT offset returning a wrong element on btree-encoded keys; negative offsets now return an empty result in both encodings by @xiaocj (#4637)
* Redact error reply text in server logs when `hide-user-data-from-log` is enabled, so keys and values no longer leak into logs via error messages by @zackcam (#4815)
* Fix cluster config saving to avoid publishing truncated `nodes.conf` files, losing the startup lock after the first save, and failing every save on SMB filesystems such as Azure Files; the lock now lives on a separate `nodes.conf.lock` file by @KewangZhili (#4489)
* Fix `LSET` on 64-bit builds silently modifying the wrong element for out-of-range indexes instead of returning an index out of range error by @charsyam (#4823)
