| CVE-2023-28320 | 3 Apple, Haxx, Netapp | 12 Macos, Curl, Clustered Data Ontap and 9 more | 2025-01-15 | 5.9 Medium |
| A denial of service vulnerability exists in curl <v8.1.0 in the way libcurl provides several different backends for resolving host names, selected at build time. If it is built to use the synchronous resolver, it allows name resolves to time-out slow operations using `alarm()` and `siglongjmp()`. When doing this, libcurl used a global buffer that was not mutex protected and a multi-threaded application might therefore crash or otherwise misbehave. | ||||
| CVE-2023-28319 | 4 Apple, Haxx, Netapp and 1 more | 13 Macos, Curl, Clustered Data Ontap and 10 more | 2025-01-15 | 7.5 High |
| A use after free vulnerability exists in curl <v8.1.0 in the way libcurl offers a feature to verify an SSH server's public key using a SHA 256 hash. When this check fails, libcurl would free the memory for the fingerprint before it returns an error message containing the (now freed) hash. This flaw risks inserting sensitive heap-based data into the error message that might be shown to users or otherwise get leaked and revealed. | ||||
| CVE-2024-9681 | 2 Curl, Haxx | 2 Curl, Curl | 2024-12-13 | 5.9 Medium |
| When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache entry, making it end sooner or later than otherwise intended. This affects curl using applications that enable HSTS and use URLs with the insecure `HTTP://` scheme and perform transfers with hosts like `x.example.com` as well as `example.com` where the first host is a subdomain of the second host. (The HSTS cache either needs to have been populated manually or there needs to have been previous HTTPS accesses done as the cache needs to have entries for the domains involved to trigger this problem.) When `x.example.com` responds with `Strict-Transport-Security:` headers, this bug can make the subdomain's expiry timeout *bleed over* and get set for the parent domain `example.com` in curl's HSTS cache. The result of a triggered bug is that HTTP accesses to `example.com` get converted to HTTPS for a different period of time than what was asked for by the origin server. If `example.com` for example stops supporting HTTPS at its expiry time, curl might then fail to access `http://example.com` until the (wrongly set) timeout expires. This bug can also expire the parent's entry *earlier*, thus making curl inadvertently switch back to insecure HTTP earlier than otherwise intended. | ||||
| CVE-2023-28322 | 5 Apple, Fedoraproject, Haxx and 2 more | 17 Macos, Fedora, Curl and 14 more | 2024-11-21 | 3.7 Low |
| An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the second transfer. The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a POST. | ||||
| CVE-2023-27533 | 5 Fedoraproject, Haxx, Netapp and 2 more | 15 Fedora, Curl, Active Iq Unified Manager and 12 more | 2024-11-21 | 8.8 High |
| A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input, thereby enabling attackers to execute arbitrary code on the system. | ||||
| CVE-2023-23915 | 4 Haxx, Netapp, Redhat and 1 more | 13 Curl, Active Iq Unified Manager, Clustered Data Ontap and 10 more | 2024-11-21 | 6.5 Medium |
| A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality to behave incorrectly when multiple URLs are requested in parallel. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. This HSTS mechanism would however surprisingly fail when multiple transfers are done in parallel as the HSTS cache file gets overwritten by the most recentlycompleted transfer. A later HTTP-only transfer to the earlier host name would then *not* get upgraded properly to HSTS. | ||||
| CVE-2022-43552 | 4 Apple, Haxx, Redhat and 1 more | 6 Macos, Curl, Enterprise Linux and 3 more | 2024-11-21 | 5.9 Medium |
| 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-2022-42916 | 5 Apple, Fedoraproject, Haxx and 2 more | 5 Macos, Fedora, Curl and 2 more | 2024-11-21 | 7.5 High |
| In curl before 7.86.0, the HSTS check could be bypassed to trick it into staying with HTTP. Using its HSTS support, curl can be instructed to use HTTPS directly (instead of using an insecure cleartext HTTP step) even when HTTP is provided in the URL. This mechanism could be bypassed if the host name in the given URL uses IDN characters that get replaced with ASCII counterparts as part of the IDN conversion, e.g., using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop of U+002E (.). The earliest affected version is 7.77.0 2021-05-26. | ||||
| CVE-2022-42915 | 6 Apple, Fedoraproject, Haxx and 3 more | 14 Macos, Fedora, Curl and 11 more | 2024-11-21 | 8.1 High |
| curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200 status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0. | ||||
| CVE-2022-35260 | 4 Apple, Haxx, Netapp and 1 more | 12 Macos, Curl, Clustered Data Ontap and 9 more | 2024-11-21 | 6.5 Medium |
| curl can be told to parse a `.netrc` file for credentials. If that file endsin a line with 4095 consecutive non-white space letters and no newline, curlwould first read past the end of the stack-based buffer, and if the readworks, write a zero byte beyond its boundary.This will in most cases cause a segfault or similar, but circumstances might also cause different outcomes.If a malicious user can provide a custom netrc file to an application or otherwise affect its contents, this flaw could be used as denial-of-service. | ||||
| CVE-2022-35252 | 6 Apple, Debian, Haxx and 3 more | 21 Macos, Debian Linux, Curl and 18 more | 2024-11-21 | 3.7 Low |
| When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control codes that when later are sent back to a HTTPserver might make the server return 400 responses. Effectively allowing a"sister site" to deny service to all siblings. | ||||
| CVE-2022-32221 | 6 Apple, Debian, Haxx and 3 more | 16 Macos, Debian Linux, Curl and 13 more | 2024-11-21 | 9.8 Critical |
| When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously was used to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST. | ||||
| CVE-2022-32208 | 7 Apple, Debian, Fedoraproject and 4 more | 21 Macos, Debian Linux, Fedora and 18 more | 2024-11-21 | 5.9 Medium |
| When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client. | ||||
| CVE-2022-32206 | 7 Debian, Fedoraproject, Haxx and 4 more | 35 Debian Linux, Fedora, Curl and 32 more | 2024-11-21 | 6.5 Medium |
| curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors. | ||||
| CVE-2022-32205 | 7 Apple, Debian, Fedoraproject and 4 more | 29 Macos, Debian Linux, Fedora and 26 more | 2024-11-21 | 4.3 Medium |
| A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method. | ||||
| CVE-2022-30115 | 3 Haxx, Netapp, Splunk | 15 Curl, Clustered Data Ontap, H300s and 12 more | 2024-11-21 | 4.3 Medium |
| Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in the given URL used atrailing dot while not using one when it built the HSTS cache. Or the otherway around - by having the trailing dot in the HSTS cache and *not* using thetrailing dot in the URL. | ||||
| CVE-2022-27782 | 4 Debian, Haxx, Redhat and 1 more | 4 Debian Linux, Curl, Enterprise Linux and 1 more | 2024-11-21 | 7.5 High |
| libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily. | ||||
| CVE-2022-27781 | 5 Debian, Haxx, Netapp and 2 more | 17 Debian Linux, Curl, Clustered Data Ontap and 14 more | 2024-11-21 | 7.5 High |
| libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation. | ||||
| CVE-2022-27780 | 3 Haxx, Netapp, Splunk | 15 Curl, Clustered Data Ontap, H300s and 12 more | 2024-11-21 | 7.5 High |
| The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more. | ||||
| CVE-2022-27779 | 3 Haxx, Netapp, Splunk | 15 Curl, Clustered Data Ontap, H300s and 12 more | 2024-11-21 | 5.3 Medium |
| libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a trailing dot.curl can be told to receive and send cookies. curl's "cookie engine" can bebuilt with or without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then would get sent to adifferent and unrelated site or domain. | ||||
