CVE-2020-8286

TITLE

Debian Security Advisory 4881-1

DESCRIPTION

curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to insufficient verification of the OCSP response. HAXX libcurl is an open source client-side URL transfer library developed by Haxx (HAXX) in Sweden. The product supports protocols such as FTP, SFTP, TFTP and HTTP. A security vulnerability exists in libcurl that could be exploited by an attacker to read or write data in a session by acting as a man-in-the-middle through low-level OCSP authentication on libcurl. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4881-1 security@debian.org https://www.debian.org/security/ Alessandro Ghedini March 30, 2021 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : curl CVE ID : CVE-2020-8169 CVE-2020-8177 CVE-2020-8231 CVE-2020-8284 CVE-2020-8285 CVE-2020-8286 CVE-2021-22876 CVE-2021-22890 Debian Bug : 965280 965281 968831 977161 977162 977163 Multiple vulnerabilities were discovered in cURL, an URL transfer library: CVE-2020-8169 Marek Szlagor reported that libcurl could be tricked into prepending a part of the password to the host name before it resolves it, potentially leaking the partial password over the network and to the DNS server(s). CVE-2020-8177 sn reported that curl could be tricked by a malicious server into overwriting a local file when using th -J (--remote-header-name) and -i (--include) options in the same command line. CVE-2020-8231 Marc Aldorasi reported that libcurl might use the wrong connection when an application using libcurl's multi API sets the option CURLOPT_CONNECT_ONLY, which could lead to information leaks. CVE-2020-8284 Varnavas Papaioannou reported that a malicious server could use the PASV response to trick curl into connecting back to an arbitrary IP address and port, potentially making curl extract information about services that are otherwise private and not disclosed. CVE-2020-8285 xnynx reported that libcurl could run out of stack space when using tha FTP wildcard matching functionality (CURLOPT_CHUNK_BGN_FUNCTION). CVE-2020-8286 It was reported that libcurl didn't verify that an OCSP response actually matches the certificate it is intended to. CVE-2021-22876 Viktor Szakats reported that libcurl does not strip off user credentials from the URL when automatically populating the Referer HTTP request header field in outgoing HTTP requests. CVE-2021-22890 Mingtao Yang reported that, when using an HTTPS proxy and TLS 1.3, libcurl could confuse session tickets arriving from the HTTPS proxy as if they arrived from the remote server instead. This could allow an HTTPS proxy to trick libcurl into using the wrong session ticket for the host and thereby circumvent the server TLS certificate check. For the stable distribution (buster), these problems have been fixed in version 7.64.0-4+deb10u2. We recommend that you upgrade your curl packages.
