Synopsis
The remote Red Hat Enterprise Linux 7 host is affected by a vulnerability in curl.Description
The remote Red Hat Enterprise Linux 7 host has a curl package installed that is affected by a vulnerability:- A use after free vulnerability exists in curl <7.87.0. 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. (CVE-2022-43552)
Note that Red Hat considers the RHEL 7 curl package to be out of support scope so no fixed update is expected.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
