high Tenable Cloud Security Plugin ID 476246

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - By default, curl automatically responds to WebSocket PING frames. Because curl lacks an upper bound on
 memory allocation for unacknowledged frames, a malicious server can exhaust all available memory by
 flooding curl with rapid, sequential PING messages. (CVE-2026-11586)

Solution

Update the curl-8.17.0 library and its related packages to version 8.17.0+e1 or later.
