This update for curl fixes the following issues :

CVE-2021-22890: TLS 1.3 session ticket proxy host mixup (bsc#1183934)

CVE-2021-22876: Automatic referer leaks credentials (bsc#1183933)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Fedora 33 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-cab5c9befb advisory.

  - curl 7.1.1 to and including 7.75.0 is vulnerable to an Exposure of Private Personal Information to an     Unauthorized Actor by leaking credentials in the HTTP Referer: header. libcurl does not strip off user     credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing     HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second     HTTP request. (CVE-2021-22876)

  - curl 7.63.0 to and including 7.75.0 includes vulnerability that allows a malicious HTTPS proxy to MITM a     connection due to bad handling of TLS 1.3 session tickets. When using a HTTPS proxy and TLS 1.3, libcurl     can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote     server and then wrongly short-cut the host handshake. When confusing the tickets, a HTTPS proxy can     trick libcurl to use the wrong session ticket resume for the host and thereby circumvent the server TLS     certificate check and make a MITM attack to be possible to perform unnoticed. Note that such a malicious     HTTPS proxy needs to provide a certificate that curl will accept for the MITMed server for an attack to     work - unless curl has been told to ignore the server certificate check. (CVE-2021-22890)

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

This update for curl fixes the following issues :

CVE-2021-22876: Fixed an issue where the automatic referer was leaking credentials (bsc#1183933).

(CVE-2021-22876)

  - libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of     them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert'     into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing     wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary     depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can     setto qualify how to verify the server certificate. (CVE-2021-22924)

  - curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used     option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for     sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer     to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-     text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing     the string provided by the application.

According to the versions of the curl packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - curl 7.1.1 to and including 7.75.0 is vulnerable to an 'Exposure of Private Personal Information to an     Unauthorized Actor' by leaking credentials in the HTTP Referer: header. libcurl does not strip off user     credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing     HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second     HTTP request. (CVE-2021-22876)

  - curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the     code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected     cipher set was stored in a single 'static' variable in the library, which has the surprising side-effect     that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will     accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport     security significantly. (CVE-2021-22897)

  - curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as     `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a     flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized     data from a stack based buffer to the server, resulting in potentially revealing sensitive internal     information to the server using a clear-text network protocol. (CVE-2021-22898)

  - When curl is instructed to download content using the metalink feature, thecontents is verified against a     hash provided in the metalink XML file.The metalink XML file points out to the client how to get the same     contentfrom a set of different URLs, potentially hosted by different servers and theclient can then     download the file from one or several of them. In a serial orparallel manner.If one of the servers hosting     the contents has been breached and the contentsof the specific file on that server is replaced with a     modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload.
    It should remove the contents and instead try getting the contentsfrom another URL. This is not done, and     instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the     file ondisk. (CVE-2021-22922)

  - When curl is instructed to get content using the metalink feature, and a user name and password are used     to download the metalink XML file, those same credentials are then subsequently passed on to each of the     servers from which curl will download or try to download the contents from. Often contrary to the user's     expectations and intentions and without telling the user it happened. (CVE-2021-22923)

  - libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of     them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert'     into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing     wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary     depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can     setto qualify how to verify the server certificate.

The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the SVD-2023-0808 advisory.

  - The go command may execute arbitrary code at build time when using cgo. This may occur when running go     get on a malicious module, or when running any other command which builds untrusted code. This is can by     triggered by linker flags, specified via a #cgo LDFLAGS directive. Flags containing embedded spaces are     mishandled, allowing disallowed flags to be smuggled through the LDFLAGS sanitization by including them in     the argument of another flag. This only affects usage of the gccgo compiler. (CVE-2023-29405)

  - When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by     finalizing the operation with a rename from a temporary name to the final target file name.In that rename     operation, it might accidentally *widen* the permissions for the target file, leaving the updated file     accessible to more users than intended. (CVE-2022-32207)

  - decode-uri-component 0.2.0 is vulnerable to Improper Input Validation resulting in DoS. (CVE-2022-38900)

  - The got package before 12.1.0 (also fixed in 11.8.5) for Node.js allows a redirect to a UNIX socket.
    (CVE-2022-33987)

  - Prototype pollution vulnerability in function parseQuery in parseQuery.js in webpack loader-utils via the     name variable in parseQuery.js. This affects all versions prior to 1.4.1 and 2.0.3. (CVE-2022-37601)
