ID CVE-2014-3707
Summary 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.

Impact:
Exploitability:
CWE CWE-200
CAPEC
  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
  • Reusing Session IDs (aka Session Replay)
    This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
  • Using Slashes in Alternate Encoding
    This attack targets the encoding of the Slash characters. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.

  • NASL family SuSE Local Security Checks
    NASL id OPENSUSE-2015-125.NASL
    description was updated to version 7.40.0 to fix two security issues. These security issues were fixed : - CVE-2014-8150: CRLF injection vulnerability in libcurl 6.0 through 7.x before 7.40.0, when using an HTTP proxy, allowed remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via CRLF sequences in a URL (bnc#911363). - CVE-2014-3707: The curl_easy_duphandle function in libcurl 7.17.1 through 7.38.0, when running with the CURLOPT_COPYPOSTFIELDS option, did not properly copy HTTP POST data for an easy handle, which triggered an out-of-bounds read that allowed remote web servers to read sensitive memory information (bnc#901924). These non-security issues were fixed : - http_digest: Added support for Windows SSPI based authentication - version info: Added Kerberos V5 to the supported features - Makefile: Added VC targets for WinIDN - SSL: Add PEM format support for public key pinning - smtp: Added support for the conversion of Unix newlines during mail send - smb: Added initial support for the SMB/CIFS protocol - Added support for HTTP over unix domain sockets, - via CURLOPT_UNIX_SOCKET_PATH and --unix-socket - sasl: Added support for GSS-API based Kerberos V5 authentication

    description Updated curl packages fix security vulnerabilities : Paras Sethia discovered that libcurl would sometimes mix up multiple HTTP and HTTPS connections with NTLM authentication to the same server, sending requests for one user over the connection authenticated as a different user (CVE-2014-0015). libcurl can in some circumstances re-use the wrong connection when asked to do transfers using other protocols than HTTP and FTP, causing a transfer that was initiated by an application to wrongfully re-use an existing connection to the same server that was authenticated using different credentials (CVE-2014-0138). libcurl incorrectly validates wildcard SSL certificates containing literal IP addresses, so under certain conditions, it would allow and use a wildcard match specified in the CN field, allowing a malicious server to participate in a MITM attack or just fool users into believing that it is a legitimate site (CVE-2014-0139). In cURL before 7.38.0, libcurl can be fooled to both sending cookies to wrong sites and into allowing arbitrary sites to set cookies for others. For this problem to trigger, the client application must use the numerical IP address in the URL to access the site (CVE-2014-3613). In cURL before 7.38.0, libcurl wrongly allows cookies to be set for Top Level Domains (TLDs), thus making them apply broader than cookies are allowed. This can allow arbitrary sites to set cookies that then would get sent to a different and unrelated site or domain (CVE-2014-3620). Symeon Paraschoudis discovered that the curl_easy_duphandle() function in cURL has a bug that can lead to libcurl eventually sending off sensitive data that was not intended for sending, while performing a HTTP POST operation. This bug requires CURLOPT_COPYPOSTFIELDS and curl_easy_duphandle() to be used in that order, and then the duplicate handle must be used to perform the HTTP POST. The curl command line tool is not affected by this problem as it does not use this sequence (CVE-2014-3707). When libcurl sends a request to a server via a HTTP proxy, it copies the entire URL into the request and sends if off. If the given URL contains line feeds and carriage returns those will be sent along to the proxy too, which allows the program to for example send a separate HTTP request injected embedded in the URL (CVE-2014-8150).

    NASL id REDHAT-RHSA-2015-1254.NASL
    description Updated curl packages that fix multiple security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. It was found that the libcurl library did not correctly handle partial literal IP addresses when parsing received HTTP cookies. An attacker able to trick a user into connecting to a malicious server could use this flaw to set the user's cookie to a crafted domain, making other cookie-related issues easier to exploit. (CVE-2014-3613) A flaw was found in the way the libcurl library performed the duplication of connection handles. If an application set the CURLOPT_COPYPOSTFIELDS option for a handle, using the handle's duplicate could cause the application to crash or disclose a portion of its memory. (CVE-2014-3707) It was discovered that the libcurl library failed to properly handle URLs with embedded end-of-line characters. An attacker able to make an application using libcurl to access a specially crafted URL via an HTTP proxy could use this flaw to inject additional headers to the request or construct additional requests. (CVE-2014-8150) It was discovered that libcurl implemented aspects of the NTLM and Negotiate authentication incorrectly. If an application uses libcurl and the affected mechanisms in a specific way, certain requests to a previously NTLM-authenticated server could appears as sent by the wrong authenticated user. Additionally, the initial set of credentials for HTTP Negotiate-authenticated requests could be reused in subsequent requests, although a different set of credentials was specified. (CVE-2015-3143, CVE-2015-3148) Red Hat would like to thank the cURL project for reporting these issues. Bug fixes : * An out-of-protocol fallback to SSL version 3.0 (SSLv3.0) was available with libcurl. Attackers could abuse the fallback to force downgrade of the SSL version. The fallback has been removed from libcurl. Users requiring this functionality can explicitly enable SSLv3.0 through the libcurl API. (BZ#1154059) * A single upload transfer through the FILE protocol opened the destination file twice. If the inotify kernel subsystem monitored the file, two events were produced unnecessarily. The file is now opened only once per upload. (BZ#883002) * Utilities using libcurl for SCP/SFTP transfers could terminate unexpectedly when the system was running in FIPS mode. (BZ#1008178) * Using the '--retry' option with the curl utility could cause curl to terminate unexpectedly with a segmentation fault. Now, adding '--retry' no longer causes curl to crash. (BZ#1009455) * The 'curl --trace-time' command did not use the correct local time when printing timestamps. Now, 'curl --trace-time' works as expected. (BZ#1120196) * The valgrind utility could report dynamically allocated memory leaks on curl exit. Now, curl performs a global shutdown of the NetScape Portable Runtime (NSPR) library on exit, and valgrind no longer reports the memory leaks. (BZ#1146528) * Previously, libcurl returned an incorrect value of the CURLINFO_HEADER_SIZE field when a proxy server appended its own headers to the HTTP response. Now, the returned value is valid. (BZ#1161163) Enhancements : * The '--tlsv1.0', '--tlsv1.1', and '--tlsv1.2' options are available for specifying the minor version of the TLS protocol to be negotiated by NSS. The '--tlsv1' option now negotiates the highest version of the TLS protocol supported by both the client and the server. (BZ#1012136) * It is now possible to explicitly enable or disable the ECC and the new AES cipher suites to be used for TLS. (BZ#1058767, BZ#1156422) All curl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.

If an application uses libcurl and the affected mechanisms in a specifc way, certain requests to a previously NTLM-authenticated server could appears as sent by the wrong authenticated user. Additionally, the initial set of credentials for HTTP Negotiate- authenticated requests could be reused in subsequent requests, although a different set of credentials was specified. (CVE-2015-3143, CVE-2015-3148) Bug fixes : - An out-of-protocol fallback to SSL 3.0 was available with libcurl. Attackers could abuse the fallback to force downgrade of the SSL version. The fallback has been removed from libcurl. Users requiring this functionality can explicitly enable SSL 3.0 through the libcurl API. - TLS 1.1 and TLS 1.2 are no longer disabled by default in libcurl. You can explicitly disable them through the libcurl API. - FTP operations such as downloading files took a significantly long time to complete. Now, the FTP implementation in libcurl correctly sets blocking direction and estimated timeout for connections, resulting in faster FTP transfers. Enhancements : - With the updated packages, it is possible to explicitly enable or disable new Advanced Encryption Standard (AES) cipher suites to be used for the TLS protocol. - The libcurl library did not implement a non-blocking SSL handshake, which negatively affected performance of applications based on the libcurl multi API. The non-blocking SSL handshake has been implemented in libcurl, and the libcurl multi API now immediately returns the control back to the application whenever it cannot read or write data from or to the underlying network socket. - The libcurl library used an unnecessarily long blocking delay for actions with no active file descriptors, even for short operations. Some actions, such as resolving a host name using /etc/hosts, took a long time to complete. The blocking code in libcurl has been modified so that the initial delay is short and gradually increases until an event occurs.

    title Scientific Linux Security Update : curl on SL7.x x86_64
  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2015-2159.NASL
    description Updated curl packages that fix multiple security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. It was found that the libcurl library did not correctly handle partial literal IP addresses when parsing received HTTP cookies. An attacker able to trick a user into connecting to a malicious server could use this flaw to set the user's cookie to a crafted domain, making other cookie-related issues easier to exploit. (CVE-2014-3613) A flaw was found in the way the libcurl library performed the duplication of connection handles. If an application set the CURLOPT_COPYPOSTFIELDS option for a handle, using the handle's duplicate could cause the application to crash or disclose a portion of its memory. (CVE-2014-3707) It was discovered that the libcurl library failed to properly handle URLs with embedded end-of-line characters. An attacker able to make an application using libcurl access a specially crafted URL via an HTTP proxy could use this flaw to inject additional headers to the request or construct additional requests.

(CVE-2015-3143, CVE-2015-3148) Red Hat would like to thank the cURL project for reporting these issues. Bug fixes : * An out-of-protocol fallback to SSL 3.0 was available with libcurl.

    description From Red Hat Security Advisory 2015:1254 : Updated curl packages that fix multiple security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6.

(CVE-2015-3143, CVE-2015-3148) Red Hat would like to thank the cURL project for reporting these issues. Bug fixes : * An out-of-protocol fallback to SSL version 3.0 (SSLv3.0) was available with libcurl. Attackers could abuse the fallback to force downgrade of the SSL version. The fallback has been removed from libcurl. Users requiring this functionality can explicitly enable SSLv3.0 through the libcurl API. (BZ#1154059) * A single upload transfer through the FILE protocol opened the destination file twice. If the inotify kernel subsystem monitored the file, two events were produced unnecessarily. The file is now opened only once per upload. (BZ#883002) * Utilities using libcurl for SCP/SFTP transfers could terminate unexpectedly when the system was running in FIPS mode. (BZ#1008178) * Using the '--retry' option with the curl utility could cause curl to terminate unexpectedly with a segmentation fault. Now, adding '--retry' no longer causes curl to crash. (BZ#1009455) * The 'curl --trace-time' command did not use the correct local time when printing timestamps. Now, 'curl --trace-time' works as expected. (BZ#1120196) * The valgrind utility could report dynamically allocated memory leaks on curl exit. Now, curl performs a global shutdown of the NetScape Portable Runtime (NSPR) library on exit, and valgrind no longer reports the memory leaks. (BZ#1146528) * Previously, libcurl returned an incorrect value of the CURLINFO_HEADER_SIZE field when a proxy server appended its own headers to the HTTP response. Now, the returned value is valid. (BZ#1161163) Enhancements : * The '--tlsv1.0', '--tlsv1.1', and '--tlsv1.2' options are available for specifying the minor version of the TLS protocol to be negotiated by NSS. The '--tlsv1' option now negotiates the highest version of the TLS protocol supported by both the client and the server. (BZ#1012136) * It is now possible to explicitly enable or disable the ECC and the new AES cipher suites to be used for TLS. (BZ#1058767, BZ#1156422) All curl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.
