critical Nessus Plugin ID 248047

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- The net/http package improperly accepts a bare LF as a line terminator in chunked data chunk-size lines.
This can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext. (CVE-2025-22871)

Note that Nessus relies on the presence of the package as reported by the vendor.
