TITLE

HAXX libcurl Security hole

DESCRIPTION

curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing. 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 trigger a fatal error via libcurl's FTP wildcards, thereby triggering a denial of service. A security issue was found in curl versions 7.21.0 up to and including 7.73.0. libcurl offers a wildcard matching functionality, which allows a callback (set with CURLOPT_CHUNK_BGN_FUNCTION) to return information back to libcurl on how to handle a specific entry in a directory when libcurl iterates over a list of all available entries. When this callback returns CURL_CHUNK_BGN_FUNC_SKIP, to tell libcurl to not deal with that file, the internal function in libcurl then calls itself recursively to handle the next directory entry. If there's a sufficient amount of file entries and if the callback returns "skip" enough number of times, libcurl runs out of stack space. The exact amount will of course vary with platforms, compilers and other environmental factors. The content of the remote directory is not kept on the stack, so it seems hard for the malicious user to control exactly what data that overwrites the stack - however it remains a Denial-Of-Service vector as a malicious user who controls a server that a libcurl-using application works with under these premises can trigger a crash. Description: This release adds the new Apache HTTP Server 2.4.37 Service Pack 8 packages that are part of the JBoss Core Services offering. This release serves as a replacement for Red Hat JBoss Core Services Pack Apache Server 2.4.37 Service Pack 7 and includes bug fixes and enhancements. Refer to the Release Notes for information on the most significant bug fixes and enhancements included in this release. Security Fix(es): * curl: Use-after-free in TLS session handling when using OpenSSL TLS backend (CVE-2021-22901) * httpd: NULL pointer dereference on specially crafted HTTP/2 request (CVE-2021-31618) * libcurl: partial password leak over DNS on HTTP redirect (CVE-2020-8169) * 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) * curl: Leak of authentication credentials in URL via automatic Referer (CVE-2021-22876) * curl: TLS 1.3 session ticket mix-up with HTTPS proxy host (CVE-2021-22890) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Software Description: - curl: HTTP, HTTPS, and FTP client and client libraries Details: Marc Aldorasi discovered that curl incorrectly handled the libcurl CURLOPT_CONNECT_ONLY option. This could result in data being sent to the wrong destination, possibly exposing sensitive information. This issue only affected Ubuntu 20.10. (CVE-2020-8231) Varnavas Papaioannou discovered that curl incorrectly handled FTP PASV responses. An attacker could possibly use this issue to trick curl into connecting to an arbitrary IP address and be used to perform port scanner and other information gathering. (CVE-2020-8284) It was discovered that curl incorrectly handled FTP wildcard matchins.
