CVE-2023-27533 4 Fedoraproject, Haxx, Netapp and 1 more 13 Fedora, Curl, Active Iq Unified Manager and 10 more 2024-03-27 N/A 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-2023-27534 5 Broadcom, Fedoraproject, Haxx and 2 more 13 Brocade Fabric Operating System Firmware, Fedora, Curl and 10 more 2024-03-27 N/A 8.8 HIGH
A path traversal vulnerability exists in curl <8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory. Attackers can exploit this flaw to bypass filtering or execute arbitrary code by crafting a path like /~2/foo while accessing a server with a specific user.
CVE-2005-0490 1 Haxx 2 Curl, Libcurl 2024-02-02 5.1 MEDIUM 8.8 HIGH
Multiple stack-based buffer overflows in libcURL and cURL 7.12.1, and possibly other versions, allow remote malicious web servers to execute arbitrary code via base64 encoded replies that exceed the intended buffer lengths when decoded, which is not properly handled by (1) the Curl_input_ntlm function in http_ntlm.c during NTLM authentication or (2) the Curl_krb_kauth and krb4_auth functions in krb4.c during Kerberos authentication.
CVE-2023-46218 2 Fedoraproject, Haxx 2 Fedora, Curl 2024-01-25 N/A 6.5 MEDIUM
This flaw allows a malicious HTTP server to set "super cookies" in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain.
CVE-2023-46219 2 Fedoraproject, Haxx 2 Fedora, Curl 2024-01-19 N/A 5.3 MEDIUM
When saving HSTS data to an excessively long file name, curl could end up removing all contents, making subsequent requests using that file unaware of the HSTS status they should otherwise use.
CVE-2023-28322 4 Apple, Fedoraproject, Haxx and 1 more 13 Macos, Fedora, Curl and 10 more 2023-12-22 N/A 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-2016-9952 2 Haxx, Microsoft 2 Curl, Windows Embedded Compact 2023-12-15 6.8 MEDIUM 8.1 HIGH
The verify_certificate function in lib/vtls/schannel.c in libcurl 7.30.0 through 7.51.0, when built for Windows CE using the schannel TLS backend, makes it easier for remote attackers to conduct man-in-the-middle attacks via a crafted wildcard SAN in a server certificate, as demonstrated by "*.com."
CVE-2016-9953 2 Haxx, Microsoft 2 Curl, Windows Embedded Compact 2023-12-15 7.5 HIGH 9.8 CRITICAL
The verify_certificate function in lib/vtls/schannel.c in libcurl 7.30.0 through 7.51.0, when built for Windows CE using the schannel TLS backend, allows remote attackers to obtain sensitive information, cause a denial of service (crash), or possibly have unspecified other impact via a wildcard certificate name, which triggers an out-of-bounds read.
CVE-2023-28321 5 Apple, Debian, Fedoraproject and 2 more 14 Macos, Debian Linux, Fedora and 11 more 2023-12-10 N/A 5.9 MEDIUM
An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. curl can be built to use its own name matching function for TLS rather than one provided by a TLS library. This private wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to pattern match, but the wildcard check in curl could still check for `x*`, which would match even though the IDN name most likely contained nothing even resembling an `x`.
CVE-2023-28320 3 Apple, Haxx, Netapp 12 Macos, Curl, Clustered Data Ontap and 9 more 2023-12-10 N/A 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 3 Apple, Haxx, Netapp 12 Macos, Curl, Clustered Data Ontap and 9 more 2023-12-10 N/A 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-2016-4606 2 Apple, Haxx 2 Mac Os X, Curl 2023-12-10 7.5 HIGH 9.8 CRITICAL
Curl before 7.49.1 in Apple OS X before macOS Sierra prior to 10.12 allows remote or local attackers to execute arbitrary code, gain sensitive information, cause denial-of-service conditions, bypass security restrictions, and perform unauthorized actions. This may aid in other attacks.
CVE-2019-5435 1 Haxx 1 Curl 2023-12-10 4.3 MEDIUM 3.7 LOW
An integer overflow in curl's URL API results in a buffer overflow in libcurl 7.62.0 to and including 7.64.1.
CVE-2019-5482 6 Debian, Fedoraproject, Haxx and 3 more 17 Debian Linux, Fedora, Curl and 14 more 2023-12-10 7.5 HIGH 9.8 CRITICAL
Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3.
CVE-2019-5443 4 Haxx, Microsoft, Netapp and 1 more 10 Curl, Windows, Oncommand Insight and 7 more 2023-12-10 4.4 MEDIUM 7.8 HIGH
A non-privileged user or program can put code and a config file in a known non-privileged path (under C:/usr/local/) that will make curl <= 7.65.1 automatically run the code (as an openssl "engine") on invocation. If that curl is invoked by a privileged user it can do anything it wants.
CVE-2019-5481 6 Debian, Fedoraproject, Haxx and 3 more 13 Debian Linux, Fedora, Curl and 10 more 2023-12-10 7.5 HIGH 9.8 CRITICAL
Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3.
CVE-2016-8620 1 Haxx 1 Curl 2023-12-10 7.5 HIGH 9.8 CRITICAL
The 'globbing' feature in curl before version 7.51.0 has a flaw that leads to integer overflow and out-of-bounds read via user controlled input.
CVE-2018-16840 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2023-12-10 7.5 HIGH 9.8 CRITICAL
A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the `Curl_close()` function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.
CVE-2016-8623 1 Haxx 1 Curl 2023-12-10 5.0 MEDIUM 7.5 HIGH
A flaw was found in curl before version 7.51.0. The way curl handles cookies permits other threads to trigger a use-after-free leading to information disclosure.
CVE-2016-8617 1 Haxx 1 Curl 2023-12-10 4.4 MEDIUM 7.0 HIGH
The base64 encode function in curl before version 7.51.0 is prone to a buffer being under allocated in 32bit systems if it receives at least 1Gb as input via `CURLOPT_USERNAME`.
