CVE-2017-1000257 | 3 Debian, Haxx, Redhat | 5 Debian Linux, Libcurl, Enterprise Linux and 2 more | 2025-04-20 | N/A |
An IMAP FETCH response line indicates the size of the returned data, in number of bytes. When that response says the data is zero bytes, libcurl would pass on that (non-existing) data with a pointer and the size (zero) to the deliver-data function. libcurl's deliver-data function treats zero as a magic number and invokes strlen() on the data to figure out the length. The strlen() is called on a heap based buffer that might not be zero terminated so libcurl might read beyond the end of it into whatever memory lies after (or just crash) and then deliver that to the application as if it was actually downloaded. | ||||
CVE-2017-1000101 | 2 Haxx, Redhat | 2 Curl, Rhel Software Collections | 2025-04-20 | N/A |
curl supports "globbing" of URLs, in which a user can pass a numerical range to have the tool iterate over those numbers to do a sequence of transfers. In the globbing function that parses the numerical range, there was an omission that made curl read a byte beyond the end of the URL if given a carefully crafted, or just wrongly written, URL. The URL is stored in a heap based buffer, so it could then be made to wrongly read something else instead of crashing. An example of a URL that triggers the flaw would be `http://ur%20[0-60000000000000000000`. | ||||
CVE-2017-7407 | 2 Haxx, Redhat | 2 Curl, Rhel Software Collections | 2025-04-20 | 2.4 Low |
The ourWriteOut function in tool_writeout.c in curl 7.53.1 might allow physically proximate attackers to obtain sensitive information from process memory in opportunistic circumstances by reading a workstation screen during use of a --write-out argument ending in a '%' character, which leads to a heap-based buffer over-read. | ||||
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-2017-8817 | 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-2017-8816 | 3 Debian, Haxx, Redhat | 4 Debian Linux, Curl, Libcurl and 1 more | 2025-04-20 | N/A |
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-2017-8818 | 1 Haxx | 2 Curl, Libcurl | 2025-04-20 | N/A |
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-2017-9502 | 1 Haxx | 1 Curl | 2025-04-20 | N/A |
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-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. | ||||
CVE-2016-5419 | 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 prevent TLS session resumption when the client certificate has changed, which allows remote attackers to bypass intended restrictions by resuming a session. | ||||
CVE-2016-4802 | 1 Haxx | 1 Curl | 2025-04-12 | N/A |
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-2014-3620 | 2 Apple, Haxx | 3 Mac Os X, Curl, Libcurl | 2025-04-12 | 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-2014-3613 | 3 Apple, Haxx, Redhat | 4 Mac Os X, Curl, Libcurl and 1 more | 2025-04-12 | 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-2016-3739 | 1 Haxx | 1 Curl | 2025-04-12 | N/A |
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-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-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-2014-2522 | 2 Haxx, Microsoft | 3 Curl, Libcurl, Windows | 2025-04-12 | 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-2015-3237 | 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-2015-3236 | 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. | ||||
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. |
