Curl Use-After-Free < 7.87 (CVE-2022-43552)

medium Nessus Plugin ID 171859

Language:

Synopsis

The remote Windows host has a program that is affected by a use-after-free vulnerability.

Description

The version of Curl installed on the remote host is prior to 7.87.0. It is therefore affected by a use-after-free vulnerability. Curl can be asked to tunnel virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct after it had been freed, in its transfer shutdown code path.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade Curl to version 7.87.0 or later
