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-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-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-2014-0138 2 Debian, Haxx 3 Debian Linux, Curl, Libcurl 2025-04-12 6.4 MEDIUM 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-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-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-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-2016-5421 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-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-2015-3236 1 Haxx 2 Curl, Libcurl 2025-04-12 5.0 MEDIUM 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.
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-2011-3389 9 Canonical, Debian, Google and 6 more 17 Ubuntu Linux, Debian Linux, Chrome and 14 more 2025-04-11 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-2013-1944 2 Canonical, Haxx 3 Ubuntu Linux, Curl, Libcurl 2025-04-11 5.0 MEDIUM N/A
The tailMatch function in cookie.c in cURL and libcurl before 7.30.0 does not properly match the path domain when sending cookies, which allows remote attackers to steal cookies via a matching suffix in the domain of a URL.
CVE-2013-4545 1 Haxx 2 Curl, Libcurl 2025-04-11 4.3 MEDIUM N/A
cURL and libcurl 7.18.0 through 7.32.0, when built with OpenSSL, disables the certificate CN and SAN name field verification (CURLOPT_SSL_VERIFYHOST) when the digital signature verification (CURLOPT_SSL_VERIFYPEER) is disabled, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
CVE-2013-6422 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Libcurl 2025-04-11 4.0 MEDIUM N/A
The GnuTLS backend in libcurl 7.21.4 through 7.33.0, when disabling digital signature verification (CURLOPT_SSL_VERIFYPEER), also disables the CURLOPT_SSL_VERIFYHOST check for CN or SAN host name fields, which makes it easier for remote attackers to spoof servers and conduct man-in-the-middle (MITM) attacks.
CVE-2013-2174 4 Canonical, Haxx, Opensuse and 1 more 5 Ubuntu Linux, Curl, Libcurl and 2 more 2025-04-11 6.8 MEDIUM N/A
Heap-based buffer overflow in the curl_easy_unescape function in lib/escape.c in cURL and libcurl 7.7 through 7.30.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string ending in a "%" (percent) character.
CVE-2014-0015 1 Haxx 2 Curl, Libcurl 2025-04-11 4.0 MEDIUM N/A
cURL and libcurl 7.10.6 through 7.34.0, when more than one authentication method is enabled, re-uses NTLM connections, which might allow context-dependent attackers to authenticate as other users via a request.
CVE-2011-2192 5 Apple, Canonical, Debian and 2 more 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more 2025-04-11 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-2013-0249 2 Canonical, Haxx 3 Ubuntu Linux, Curl, Libcurl 2025-04-11 7.5 HIGH N/A
Stack-based buffer overflow in the Curl_sasl_create_digest_md5_message function in lib/curl_sasl.c in curl and libcurl 7.26.0 through 7.28.1, when negotiating SASL DIGEST-MD5 authentication, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string in the realm parameter in a (1) POP3, (2) SMTP or (3) IMAP message.
CVE-2024-32928 2 Google, Haxx 3 Nest Mini, Nest Mini Firmware, Libcurl 2025-03-14 N/A 5.9 MEDIUM
