high Tenable Cloud Security Plugin ID 476127

Description

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

 - Enabling `CURLOPT_CRLF` causes curl to advertise the raw input byte count in the `IMAP APPEND {N}` literal
 while transmitting line-ending expanded data. The server reads only $N$ bytes for the payload, causing the
 remaining overflow bytes to be interpreted and executed as pipelined IMAP commands within the
 authenticated session. (CVE-2026-87864)
