CVE-2016-8618 1 Haxx 1 Curl 2023-11-07 7.5 HIGH 9.8 CRITICAL
The libcurl API function called `curl_maprintf()` before version 7.51.0 can be tricked into doing a double-free due to an unsafe `size_t` multiplication, on systems using 32 bit `size_t` variables.
CVE-2016-8617 1 Haxx 1 Curl 2023-11-07 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`.
CVE-2016-8616 1 Haxx 1 Curl 2023-11-07 4.3 MEDIUM 5.9 MEDIUM
A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password.
CVE-2016-8615 1 Haxx 1 Curl 2023-11-07 5.0 MEDIUM 7.5 HIGH
A flaw was found in curl before version 7.51. If cookie state is written into a cookie jar file that is later read back and used for subsequent requests, a malicious HTTP server can inject new cookies for arbitrary domains into said cookie jar.
CVE-2016-7167 2 Fedoraproject, Haxx 2 Fedora, Libcurl 2023-11-07 7.5 HIGH 9.8 CRITICAL
Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl before 7.50.3 allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow.
CVE-2016-5421 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 6.8 MEDIUM 8.1 HIGH
Use-after-free vulnerability in libcurl before 7.50.1 allows attackers to control which connection is used or possibly have unspecified other impact via unknown vectors.
CVE-2016-5420 3 Debian, Haxx, Opensuse 3 Debian Linux, Libcurl, Leap 2023-11-07 5.0 MEDIUM 7.5 HIGH
curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.
CVE-2016-5419 3 Debian, Haxx, Opensuse 3 Debian Linux, Libcurl, Leap 2023-11-07 5.0 MEDIUM 7.5 HIGH
curl and libcurl before 7.50.1 do not prevent TLS session resumption when the client certificate has changed, which allows remote attackers to bypass intended restrictions by resuming a session.
CVE-2023-28319 3 Apple, Haxx, Netapp 12 Macos, Curl, Clustered Data Ontap and 9 more 2023-10-20 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-2023-28320 3 Apple, Haxx, Netapp 12 Macos, Curl, Clustered Data Ontap and 9 more 2023-10-20 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-2017-2628 2 Haxx, Redhat 4 Curl, Enterprise Linux Desktop, Enterprise Linux Server and 1 more 2023-02-12 7.5 HIGH 9.8 CRITICAL
curl, as shipped in Red Hat Enterprise Linux 6 before version 7.19.7-53, did not correctly backport the fix for CVE-2015-3148 because it did not reflect the fact that the HAVE_GSSAPI define was meanwhile substituted by USE_HTTP_NEGOTIATE. This issue was introduced in RHEL 6.7 and affects RHEL 6 curl only.
CVE-2011-3389 9 Canonical, Debian, Google and 6 more 17 Ubuntu Linux, Debian Linux, Chrome and 14 more 2022-11-29 4.3 MEDIUM N/A
The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.
CVE-2018-1000007 5 Canonical, Debian, Fujitsu and 2 more 20 Ubuntu Linux, Debian Linux, M10-1 and 17 more 2022-06-13 5.0 MEDIUM 9.8 CRITICAL
libcurl 7.1 through 7.57.0 might accidentally leak authentication data to third parties. When asked to send custom headers in its HTTP requests, libcurl will send that set of headers first to the host in the initial URL but also, if asked to follow redirects and a 30X HTTP response code is returned, to the host mentioned in URL in the `Location:` response header value. Sending the same set of headers to subsequent hosts is in particular a problem for applications that pass on custom `Authorization:` headers, as this header often contains privacy sensitive information or data that could allow others to impersonate the libcurl-using client's request.
CVE-2014-3620 2 Apple, Haxx 3 Mac Os X, Curl, Libcurl 2022-05-11 5.0 MEDIUM N/A
cURL and libcurl before 7.38.0 allow remote attackers to bypass the Same Origin Policy and set cookies for arbitrary sites by setting a cookie for a top-level domain.
CVE-2019-5443 4 Haxx, Microsoft, Netapp and 1 more 10 Curl, Windows, Oncommand Insight and 7 more 2021-11-03 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-2018-1000300 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2020-08-24 7.5 HIGH 9.8 CRITICAL
curl version curl 7.54.1 to and including curl 7.59.0 contains a CWE-122: Heap-based Buffer Overflow vulnerability in denial of service and more that can result in curl might overflow a heap based memory buffer when closing down an FTP connection with very long server command replies.. This vulnerability appears to have been fixed in curl < 7.54.1 and curl >= 7.60.0.
CVE-2018-0500 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2020-08-24 7.5 HIGH 9.8 CRITICAL
Curl_smtp_escape_eob in lib/smtp.c in curl 7.54.1 to and including curl 7.60.0 has a heap-based buffer overflow that might be exploitable by an attacker who can control the data that curl transmits over SMTP with certain settings (i.e., use of a nonstandard --limit-rate argument or CURLOPT_BUFFERSIZE value).
CVE-2011-2192 5 Apple, Canonical, Debian and 2 more 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more 2020-05-27 4.3 MEDIUM N/A
The Curl_input_negotiate function in http_negotiate.c in libcurl 7.10.6 through 7.21.6, as used in curl and other products, always performs credential delegation during GSSAPI authentication, which allows remote servers to impersonate clients via GSSAPI requests.
CVE-2016-4606 2 Apple, Haxx 2 Mac Os X, Curl 2020-02-21 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-2018-16840 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2019-10-09 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.
