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-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-2016-5420 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 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-2016-5421 6 Canonical, Debian, Fedoraproject and 3 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2025-04-12 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 3 Fedoraproject, Haxx, Redhat 5 Fedora, Libcurl, Enterprise Linux and 2 more 2025-04-12 N/A
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-2015-3148 8 Apple, Canonical, Debian and 5 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2025-04-12 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-2014-3707 7 Apple, Canonical, Debian and 4 more 7 Mac Os X, Ubuntu Linux, Debian Linux and 4 more 2025-04-12 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-2013-0249 2 Canonical, Haxx 3 Ubuntu Linux, Curl, Libcurl 2025-04-11 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-2013-2174 4 Canonical, Haxx, Opensuse and 1 more 5 Ubuntu Linux, Curl, Libcurl and 2 more 2025-04-11 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-2013-4545 1 Haxx 2 Curl, Libcurl 2025-04-11 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-2013-1944 3 Canonical, Haxx, Redhat 4 Ubuntu Linux, Curl, Libcurl and 1 more 2025-04-11 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-2013-6422 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Libcurl 2025-04-11 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-2011-2192 6 Apple, Canonical, Debian and 3 more 6 Mac Os X, Ubuntu Linux, Debian Linux and 3 more 2025-04-11 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-2014-0015 2 Haxx, Redhat 3 Curl, Libcurl, Enterprise Linux 2025-04-11 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-2005-0490 2 Haxx, Redhat 3 Curl, Libcurl, Enterprise Linux 2025-04-03 8.8 High
Multiple stack-based buffer overflows in libcURL and cURL 7.12.1, and possibly other versions, allow remote malicious web servers to execute arbitrary code via base64 encoded replies that exceed the intended buffer lengths when decoded, which is not properly handled by (1) the Curl_input_ntlm function in http_ntlm.c during NTLM authentication or (2) the Curl_krb_kauth and krb4_auth functions in krb4.c during Kerberos authentication.
CVE-2024-32928 2 Google, Haxx 3 Nest Mini, Nest Mini Firmware, Libcurl 2025-03-14 5.9 Medium
The libcurl CURLOPT_SSL_VERIFYPEER option was disabled on a subset of requests made by Nest production devices which enabled a potential man-in-the-middle attack on requests to Google cloud services by any host the traffic was routed through.
CVE-2023-27536 6 Debian, Fedoraproject, Haxx and 3 more 16 Debian Linux, Fedora, Libcurl and 13 more 2025-02-14 5.9 Medium
An authentication bypass vulnerability exists libcurl <8.0.0 in the connection reuse feature which can reuse previously established connections with incorrect user permissions due to a failure to check for changes in the CURLOPT_GSSAPI_DELEGATION option. This vulnerability affects krb5/kerberos/negotiate/GSSAPI transfers and could potentially result in unauthorized access to sensitive information. The safest option is to not reuse connections if the CURLOPT_GSSAPI_DELEGATION option has been changed.
CVE-2024-7264 2 Haxx, Redhat 3 Libcurl, Enterprise Linux, Service Mesh 2025-02-13 6.3 Medium
libcurl's ASN1 parser code has the `GTime2str()` function, used for parsing an ASN.1 Generalized Time field. If given an syntactically incorrect field, the parser might end up using -1 for the length of the *time fraction*, leading to a `strlen()` getting performed on a pointer to a heap buffer area that is not (purposely) null terminated. This flaw most likely leads to a crash, but can also lead to heap contents getting returned to the application when [CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used.
CVE-2024-6874 2 Curl, Haxx 2 Libcurl, Libcurl 2025-02-13 3.1 Low
libcurl's URL API function [curl_url_get()](https://curl.se/libcurl/c/curl_url_get.html) offers punycode conversions, to and from IDN. Asking to convert a name that is exactly 256 bytes, libcurl ends up reading outside of a stack based buffer when built to use the *macidn* IDN backend. The conversion function then fills up the provided buffer exactly - but does not null terminate the string. This flaw can lead to stack contents accidently getting returned as part of the converted string.
CVE-2024-6197 2 Curl, Haxx 2 Curl, Libcurl 2025-02-13 7.5 High
libcurl's ASN1 parser has this utf8asn1str() function used for parsing an ASN.1 UTF-8 string. Itcan detect an invalid field and return error. Unfortunately, when doing so it also invokes `free()` on a 4 byte localstack buffer. Most modern malloc implementations detect this error and immediately abort. Some however accept the input pointer and add that memory to its list of available chunks. This leads to the overwriting of nearby stack memory. The content of the overwrite is decided by the `free()` implementation; likely to be memory pointers and a set of flags. The most likely outcome of exploting this flaw is a crash, although it cannot be ruled out that more serious results can be had in special circumstances.
