CVE-2016-0754 2 Haxx, Microsoft 2 Curl, Windows 2025-04-12 5.0 MEDIUM 5.3 MEDIUM
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-2014-3707 6 Apple, Canonical, Debian and 3 more 6 Mac Os X, Ubuntu Linux, Debian Linux and 3 more 2025-04-12 4.3 MEDIUM N/A
The curl_easy_duphandle function in libcurl 7.17.1 through 7.38.0, when running with the CURLOPT_COPYPOSTFIELDS option, does not properly copy HTTP POST data for an easy handle, which triggers an out-of-bounds read that allows remote web servers to read sensitive memory information.
CVE-2016-7141 2 Haxx, Opensuse 2 Libcurl, Leap 2025-04-12 5.0 MEDIUM 7.5 HIGH
curl and libcurl before 7.50.2, when built with NSS and the libnsspem.so library is available at runtime, allow remote attackers to hijack the authentication of a TLS connection by leveraging reuse of a previously loaded client certificate from file for a connection for which no certificate has been set, a different vulnerability than CVE-2016-5420.
CVE-2016-3739 1 Haxx 1 Curl 2025-04-12 2.6 LOW 5.3 MEDIUM
The (1) mbed_connect_step1 function in lib/vtls/mbedtls.c and (2) polarssl_connect_step1 function in lib/vtls/polarssl.c in cURL and libcurl before 7.49.0, when using SSLv3 or making a TLS connection to a URL that uses a numerical IP address, allow remote attackers to spoof servers via an arbitrary valid certificate.
CVE-2015-3144 4 Canonical, Debian, Haxx and 1 more 5 Ubuntu Linux, Debian Linux, Curl and 2 more 2025-04-12 9.0 HIGH N/A
The fix_hostname function in cURL and libcurl 7.37.0 through 7.41.0 does not properly calculate an index, which allows remote attackers to cause a denial of service (out-of-bounds read or write and crash) or possibly have other unspecified impact via a zero-length host name, as demonstrated by "http://:80" and ":80."
CVE-2015-3153 5 Apple, Canonical, Debian and 2 more 6 Mac Os X, Ubuntu Linux, Debian Linux and 3 more 2025-04-12 5.0 MEDIUM N/A
The default configuration for cURL and libcurl before 7.42.1 sends custom HTTP headers to both the proxy and destination server, which might allow remote proxy servers to obtain sensitive information by reading the header contents.
CVE-2014-8150 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Libcurl 2025-04-12 4.3 MEDIUM N/A
CRLF injection vulnerability in libcurl 6.0 through 7.x before 7.40.0, when using an HTTP proxy, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via CRLF sequences in a URL.
CVE-2016-4802 1 Haxx 1 Curl 2025-04-12 6.9 MEDIUM 7.8 HIGH
Multiple untrusted search path vulnerabilities in cURL and libcurl before 7.49.1, when built with SSPI or telnet is enabled, allow local users to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse (1) security.dll, (2) secur32.dll, or (3) ws2_32.dll in the application or current working directory.
CVE-2016-5420 3 Debian, Haxx, Opensuse 3 Debian Linux, Libcurl, Leap 2025-04-12 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-2016-0755 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Curl 2025-04-12 5.0 MEDIUM 7.3 HIGH
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-2014-2522 2 Haxx, Microsoft 3 Curl, Libcurl, Windows 2025-04-12 4.0 MEDIUM N/A
curl and libcurl 7.27.0 through 7.35.0, when running on Windows and using the SChannel/Winssl TLS backend, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate when accessing a URL that uses a numerical IP address, which allows man-in-the-middle attackers to spoof servers via an arbitrary valid certificate.
CVE-2015-3148 7 Apple, Canonical, Debian and 4 more 8 Mac Os X, Ubuntu Linux, Debian Linux and 5 more 2025-04-12 5.0 MEDIUM N/A
cURL and libcurl 7.10.6 through 7.41.0 do not properly re-use authenticated Negotiate connections, which allows remote attackers to connect as other users via a request.
CVE-2016-7167 2 Fedoraproject, Haxx 2 Fedora, Libcurl 2025-04-12 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-2015-3145 8 Apple, Canonical, Debian and 5 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2025-04-12 7.5 HIGH N/A
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-2014-3613 2 Apple, Haxx 3 Mac Os X, Curl, Libcurl 2025-04-12 5.0 MEDIUM N/A
cURL and libcurl before 7.38.0 does not properly handle IP addresses in cookie domain names, which allows remote attackers to set cookies for or send arbitrary cookies to certain sites, as demonstrated by a site at 192.168.0.1 setting cookies for a site at 127.168.0.1.
CVE-2015-3237 3 Haxx, Hp, Oracle 5 Curl, Libcurl, System Management Homepage and 2 more 2025-04-12 6.4 MEDIUM 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-2016-5421 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2025-04-12 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-2014-8151 2 Apple, Haxx 2 Mac Os X, Libcurl 2025-04-12 5.8 MEDIUM 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-2015-3143 5 Apple, Canonical, Debian and 2 more 6 Mac Os X, Ubuntu Linux, Debian Linux and 3 more 2025-04-12 5.0 MEDIUM 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-2016-5419 3 Debian, Haxx, Opensuse 3 Debian Linux, Libcurl, Leap 2025-04-12 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.
