CVE-2017-9502 1 Haxx 1 Curl 2025-04-20 5.0 MEDIUM 5.3 MEDIUM
In curl before 7.54.1 on Windows and DOS, libcurl's default protocol function, which is the logic that allows an application to set which protocol libcurl should attempt to use when given a URL without a scheme part, had a flaw that could lead to it overwriting a heap based memory buffer with seven bytes. If the default protocol is specified to be FILE or a file: URL lacks two slashes, the given "URL" starts with a drive letter, and libcurl is built for Windows or DOS, then libcurl would copy the path 7 bytes off, so that the end of the given path would write beyond the malloc buffer (7 bytes being the length in bytes of the ascii string "file://").
CVE-2017-8818 1 Haxx 2 Curl, Libcurl 2025-04-20 7.5 HIGH 9.8 CRITICAL
curl and libcurl before 7.57.0 on 32-bit platforms allow attackers to cause a denial of service (out-of-bounds access and application crash) or possibly have unspecified other impact because too little memory is allocated for interfacing to an SSL library.
CVE-2018-16840 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2025-04-17 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-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-2015-3237 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-2016-5419 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.
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-2014-0139 1 Haxx 2 Curl, Libcurl 2025-04-12 5.8 MEDIUM 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-2014-3620 2 Apple, Haxx 3 Mac Os X, Curl, Libcurl 2025-04-12 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-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-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-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-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-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-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-2015-3145 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-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-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-2016-4802 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.
