Vulnerable Configurations
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.

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 last seen 2020-06-01 modified 2020-06-02 plugin id 122260 published 2019-02-19 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/122260 title Amazon Linux 2 : curl (ALAS-2019-1162) NASL family PhotonOS Local Security Checks NASL id PHOTONOS_PHSA-2018-1_0-0108_CURL.NASL description An update of the curl package has been released. last seen 2020-03-17 modified 2019-02-07 plugin id 121808 published 2019-02-07 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/121808 title Photon OS 1.0: Curl PHSA-2018-1.0-0108 NASL family Debian Local Security Checks NASL id DEBIAN_DLA-1195.NASL description CVE-2017-8817 Fuzzing by the OSS-Fuzz project led to the discovery of a read out of bounds flaw in the FTP wildcard function in libcurl.

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/415d2e 7cb7), 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.i1/4^CVE-2017-1000254i1/4%0 - 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 last seen 2020-03-19 modified 2018-10-26 plugin id 118418 published 2018-10-26 reporter This script is Copyright (C) 2018-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/118418 title EulerOS Virtualization 2.5.0 : curl (EulerOS-SA-2018-1330) NASL family PhotonOS Local Security Checks NASL id PHOTONOS_PHSA-2018-1_0-0108_POSTGRESQL.NASL description An update of the postgresql package has been released. last seen 2020-03-17 modified 2019-02-07 plugin id 121809 published 2019-02-07 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/121809 title Photon OS 1.0: Postgresql PHSA-2018-1.0-0108 NASL family PhotonOS Local Security Checks NASL id PHOTONOS_PHSA-2018-1_0-0108.NASL description An update of 'postgresql', 'curl' packages of Photon OS has been released. last seen 2019-02-21 modified 2019-02-07 plugin id 111919 published 2018-08-17 reporter Tenable source https://www.tenable.com/plugins/index.php?view=single&id=111919 title Photon OS 1.0: Curl / Postgresql PHSA-2018-1.0-0108 (deprecated) NASL family Huawei Local Security Checks NASL id EULEROS_SA-2018-1040.NASL description According to the version of the curl packages installed, the EulerOS installation on the remote host is affected by the following vulnerability : - 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 last seen 2020-05-06 modified 2018-02-13 plugin id 106768 published 2018-02-13 reporter This script is Copyright (C) 2018-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/106768 title EulerOS 2.0 SP2 : curl (EulerOS-SA-2018-1040) NASL family PhotonOS Local Security Checks NASL id PHOTONOS_PHSA-2018-2_0-0016_POSTGRESQL.NASL description An update of the postgresql package has been released. last seen 2020-03-17 modified 2019-02-07 plugin id 121919 published 2019-02-07 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/121919 title Photon OS 2.0: Postgresql PHSA-2018-2.0-0016 NASL family Fedora Local Security Checks NASL id FEDORA_2017-0C062324CD.NASL description - fix NTLM buffer overflow via integer overflow (CVE-2017-8816) - fix FTP wildcard out of bounds read (CVE-2017-8817) Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
