CVE-2016-7167 2 Fedoraproject, Haxx 2 Fedora, Libcurl 2018-11-13 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-2016-8622 1 Haxx 1 Libcurl 2018-11-13 7.5 HIGH 9.8 CRITICAL
The URL percent-encoding decode function in libcurl before 7.51.0 is called `curl_easy_unescape`. Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get either just truncated or both truncated and turned negative. That could then lead to libcurl writing outside of its heap based buffer.
CVE-2017-1000100 1 Haxx 1 Libcurl 2018-11-13 4.3 MEDIUM 6.5 MEDIUM
When doing a TFTP transfer and curl/libcurl is given a URL that contains a very long file name (longer than about 515 bytes), the file name is truncated to fit within the buffer boundaries, but the buffer size is still wrongly updated to use the untruncated length. This too large value is then used in the sendto() call, making curl attempt to send more data than what is actually put into the buffer. The endto() function will then read beyond the end of the heap based buffer. A malicious HTTP(S) server could redirect a vulnerable libcurl-using client to a crafted TFTP URL (if the client hasn't restricted which protocols it allows redirects to) and trick it to send private memory contents to a remote server over UDP. Limit curl's redirect protocols with --proto-redir and libcurl's with CURLOPT_REDIR_PROTOCOLS.
CVE-2017-8816 2 Debian, Haxx 3 Debian Linux, Curl, Libcurl 2018-11-13 7.5 HIGH 9.8 CRITICAL
The NTLM authentication feature in curl and libcurl before 7.57.0 on 32-bit platforms allows attackers to cause a denial of service (integer overflow and resultant buffer overflow, and application crash) or possibly have unspecified other impact via vectors involving long user and password fields.
CVE-2017-8817 2 Debian, Haxx 3 Debian Linux, Curl, Libcurl 2018-11-13 7.5 HIGH 9.8 CRITICAL
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-2016-5420 3 Debian, Haxx, Opensuse 3 Debian Linux, Libcurl, Leap 2018-11-13 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 2018-11-13 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-2016-7141 2 Haxx, Opensuse 2 Libcurl, Leap 2018-11-13 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-2015-3145 8 Apple, Canonical, Debian and 5 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2018-10-30 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-2014-3707 6 Apple, Canonical, Debian and 3 more 6 Mac Os X, Ubuntu Linux, Debian Linux and 3 more 2018-10-30 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-2015-3148 7 Apple, Canonical, Debian and 4 more 8 Mac Os X, Ubuntu Linux, Debian Linux and 5 more 2018-10-30 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-2015-3153 5 Apple, Canonical, Debian and 2 more 6 Mac Os X, Ubuntu Linux, Debian Linux and 3 more 2018-10-16 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-2015-3236 1 Haxx 2 Curl, Libcurl 2018-10-16 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-2015-3237 3 Haxx, Hp, Oracle 5 Curl, Libcurl, System Management Homepage and 2 more 2018-10-16 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-2015-3144 4 Canonical, Debian, Haxx and 1 more 5 Ubuntu Linux, Debian Linux, Curl and 2 more 2018-10-16 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-2014-0138 2 Debian, Haxx 3 Debian Linux, Curl, Libcurl 2018-10-09 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-2014-0015 1 Haxx 2 Curl, Libcurl 2018-10-09 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-2015-3143 5 Apple, Canonical, Debian and 2 more 6 Mac Os X, Ubuntu Linux, Debian Linux and 3 more 2018-01-04 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.

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.
