Vulnerability Title
Io.netty/netty-codec-redis: netty: redisarrayaggregator nested resp headers multiply patched preallocation limits
来源: CVE Program / CVE List V5
Vulnerability Description
## Summary
`RedisArrayAggregator` recently added `maxElements` and `maxNestedArrayDepth` limits to fix public Redis resource-exhaustion advisories. The limits are independent, but the allocator remains eager: every positive nested RESP array header creates `new ArrayList<RedisMessage>(length)` before any child element exists.
With the default constructor, an attacker can send nested array headers with length `1,000,000` until the default nesting limit of `1024` is reached. This can reserve up to `1,024,000,000` child slots from roughly 12 KB of RESP input. This is backing capacity, not logical list size: `ArrayList(int)` constructs an empty list with the specified initial capacity.
## Technical Details
Current `decodeRedisArrayHeader(...)` checks the two limits independently:
```java
if (header.length() > maxElements) {
throw new CodecException("this codec doesn't support longer length than " + maxElements);
}
if (depths.size() >= maxNestedArrayDepth) {
releaseAndClearDepths();
throw new CodecException("max nested array depth exceeded: " + maxNestedArrayDepth);
}
depths.push(new AggregateState((int) header.length()));
```
