CVE-2017-1000254 2 Haxx, Redhat 3 Libcurl, Jboss Core Services, Rhel Software Collections 2025-04-20 N/A
libcurl may read outside of a heap allocated buffer when doing FTP. When libcurl connects to an FTP server and successfully logs in (anonymous or not), it asks the server for the current directory with the `PWD` command. The server then responds with a 257 response containing the path, inside double quotes. The returned path name is then kept by libcurl for subsequent uses. Due to a flaw in the string parser for this directory name, a directory name passed like this but without a closing double quote would lead to libcurl not adding a trailing NUL byte to the buffer holding the name. When libcurl would then later access the string, it could read beyond the allocated heap buffer and crash or wrongly access data beyond the buffer, thinking it was part of the path. A malicious server could abuse this fact and effectively prevent libcurl-based clients to work with it - the PWD command is always issued on new FTP connections and the mistake has a high chance of causing a segfault. The simple fact that this has issue remained undiscovered for this long could suggest that malformed PWD responses are rare in benign servers. We are not aware of any exploit of this flaw. This bug was introduced in commit [415d2e7cb7](https://github.com/curl/curl/commit/415d2e7cb7), March 2005. In libcurl version 7.56.0, the parser always zero terminates the string but also rejects it if not terminated properly with a final double quote.
CVE-2017-1000099 1 Haxx 1 Libcurl 2025-04-20 N/A
When asking to get a file from a file:// URL, libcurl provides a feature that outputs meta-data about the file using HTTP-like headers. The code doing this would send the wrong buffer to the user (stdout or the application's provide callback), which could lead to other private data from the heap to get inadvertently displayed. The wrong buffer was an uninitialized memory area allocated on the heap and if it turned out to not contain any zero byte, it would continue and display the data following that buffer in memory.
CVE-2017-8817 3 Debian, Haxx, Redhat 4 Debian Linux, Curl, Libcurl and 1 more 2025-04-20 N/A
The FTP wildcard function in curl and libcurl before 7.57.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) or possibly have unspecified other impact via a string that ends with an '[' character.
CVE-2018-16840 3 Canonical, Haxx, Redhat 3 Ubuntu Linux, Curl, Jboss Core Services 2025-04-17 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.

The sanitize_cookie_path function in cURL and libcurl 7.31.0 through 7.41.0 does not properly calculate an index, which allows remote attackers to cause a denial of service (out-of-bounds write and crash) or possibly have other unspecified impact via a cookie path containing only a double-quote character.
CVE-2014-0138 3 Debian, Haxx, Redhat 4 Debian Linux, Curl, Libcurl and 1 more 2025-04-12 N/A
The default configuration in cURL and libcurl 7.10.6 before 7.36.0 re-uses (1) SCP, (2) SFTP, (3) POP3, (4) POP3S, (5) IMAP, (6) IMAPS, (7) SMTP, (8) SMTPS, (9) LDAP, and (10) LDAPS connections, which might allow context-dependent attackers to connect as other users via a request, a similar issue to CVE-2014-0015.
CVE-2016-7167 3 Fedoraproject, Haxx, Redhat 5 Fedora, Libcurl, Enterprise Linux and 2 more 2025-04-12 N/A
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-2016-5420 4 Debian, Haxx, Opensuse and 1 more 6 Debian Linux, Libcurl, Leap and 3 more 2025-04-12 N/A
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-2016-0754 2 Haxx, Microsoft 2 Curl, Windows 2025-04-12 N/A
cURL before 7.47.0 on Windows allows attackers to write to arbitrary files in the current working directory on a different drive via a colon in a remote file name.
CVE-2014-0139 1 Haxx 2 Curl, Libcurl 2025-04-12 N/A
cURL and libcurl 7.1 before 7.36.0, when using the OpenSSL, axtls, qsossl or gskit libraries for TLS, recognize a wildcard IP address in the subject's Common Name (CN) field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.
CVE-2016-0755 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Curl 2025-04-12 N/A
The ConnectionExists function in lib/url.c in libcurl before 7.47.0 does not properly re-use NTLM-authenticated proxy connections, which might allow remote attackers to authenticate as other users via a request, a similar issue to CVE-2014-0015.
CVE-2015-3237 3 Haxx, Hp, Oracle 5 Curl, Libcurl, System Management Homepage and 2 more 2025-04-12 N/A
The smb_request_state function in cURL and libcurl 7.40.0 through 7.42.1 allows remote SMB servers to obtain sensitive information from memory or cause a denial of service (out-of-bounds read and crash) via crafted length and offset values.
CVE-2015-3148 8 Apple, Canonical, Debian and 5 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2025-04-12 N/A

CVE-2015-3143 6 Apple, Canonical, Debian and 3 more 7 Mac Os X, Ubuntu Linux, Debian Linux and 4 more 2025-04-12 N/A
cURL and libcurl 7.10.6 through 7.41.0 does not properly re-use NTLM connections, which allows remote attackers to connect as other users via an unauthenticated request, a similar issue to CVE-2014-0015.
CVE-2014-8151 2 Apple, Haxx 2 Mac Os X, Libcurl 2025-04-12 N/A
The darwinssl_connect_step1 function in lib/vtls/curl_darwinssl.c in libcurl 7.31.0 through 7.39.0, when using the DarwinSSL (aka SecureTransport) back-end for TLS, does not check if a cached TLS session validated the certificate when reusing the session, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.

CVE-2015-3236 1 Haxx 2 Curl, Libcurl 2025-04-12 N/A
cURL and libcurl 7.40.0 through 7.42.1 send the HTTP Basic authentication credentials for a previous connection when reusing a reset (curl_easy_reset) connection handle to send a request to the same host name, which allows remote attackers to obtain sensitive information via unspecified vectors.
