high Nessus Plugin ID 149676

Synopsis

The remote Red Hat host is missing one or more security updates for curl.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1610 advisory.

- curl: Expired pointer dereference via multi API with CURLOPT_CONNECT_ONLY option set (CVE-2020-8231)

- curl: FTP PASV command response can cause curl to connect to arbitrary host (CVE-2020-8284)

- curl: Malicious FTP server can trigger stack overflow when CURLOPT_CHUNK_BGN_FUNCTION is used (CVE-2020-8285)

- curl: Inferior OCSP verification (CVE-2020-8286)
