Summary

libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

    descriptionlibcurl is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.(CVE-2018-16890) 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-2017-8816) 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-2017-8818) 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-2017-1000254) Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.(CVE-2018-16842) libcurl is vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large

    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-2017-8816)

    or possibly have unspecified other impact because too little memory is
    allocated for interfacing to an SSL library.(CVE-2017-8818)
    
    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

    without a closing double quote would lead to libcurl not adding 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-2017-1000254)
    
    Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based
    buffer over-read in the tool_msgs.c:voutf() function that may result
    in information exposure and denial of service.(CVE-2018-16842)
    
    libcurl is vulnerable to a stack-based buffer overflow. The function
    creating an outgoing NTLM type-3 header
    (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates
    the request HTTP header contents based on previously received data.
    The check that exists to prevent the local buffer from getting
    overflowed is implemented wrongly (using unsigned math) and as such it
    does not prevent the overflow from happening. This output data can
    grow larger than the local buffer if very large 'nt response' data is
    extracted from a previous NTLMv2 header provided by the malicious or
    broken HTTP server. Such a 'large value' needs to be around 1000 bytes
    or more. The actual payload data copied to the target buffer comes
    from the NTLMv2 type-2 response header.(CVE-2019-3822)
    
    libcurl is vulnerable to a heap out-of-bounds read in the code
    handling the end-of-response for SMTP. If the buffer passed to
    `smtp_endofresp()` isn't NUL terminated and contains no character
    ending the parsed number, and `len` is set to 5, then the `strtol()`
    call reads beyond the allocated buffer. The read contents will not be
    returned to the caller.(CVE-2019-3823)
    
    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-2017-8817)
    
    set_file_metadata in xattr.c in GNU Wget before 1.20.1 stores a file's
    origin URL in the user.xdg.origin.url metadata attribute of the
    extended attributes of the downloaded file, which allows local users
    to obtain sensitive information (e.g., credentials contained in the
    URL) by reading this attribute, as demonstrated by getfattr. This also
    applies to Referer information in the user.xdg.referrer.url metadata
    attribute. According to 2016-07-22 in the Wget ChangeLog,
    user.xdg.origin.url was partially based on the behavior of
    fwrite_xattr in tool_xattr.c in curl.(CVE-2018-20483)
    
    A buffer overrun flaw was found in the IMAP handler of libcurl. By
    tricking an unsuspecting user into connecting to a malicious IMAP
    server, an attacker could exploit this flaw to potentially cause
    information disclosure or crash the application.(CVE-2017-1000257)
    
    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-2018-16840)
    
    Curl versions 7.33.0 through 7.61.1 are vulnerable to a buffer overrun
    in the SASL authentication code that may lead to denial of
    service.(CVE-2018-16839)"

    descriptionAn update for curl is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) 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. Security Fix(es) : * curl: NTLM type-2 heap out-of-bounds buffer read (CVE-2018-16890) * wget: Information exposure in set_file_metadata function in xattr.c (CVE-2018-20483) * curl: NTLMv2 type-3 header stack-based buffer overflow (CVE-2019-3822) * curl: SMTP end-of-response out-of-bounds read (CVE-2019-3823) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

    descriptioncurl security problems : CVE-2018-16890: NTLM type-2 out-of-bounds buffer read libcurl contains a heap buffer out-of-bounds read flaw. The function handling incoming NTLM type-2 messages (lib/vauth/ntlm.c:ntlm_decode_type2_target) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds. CVE-2019-3822: NTLMv2 type-3 header stack-based buffer overflow libcurl contains a stack based buffer overflow vulnerability. The function creating an outgoing NTLM type-3 header (lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large
