Affected: CleanStart: curl

Security vulnerability affects the curl package. This issue is resolved in later releases. See references for vulnerability details.

A buffer overflow exists in curl 7.12.3 to and including curl 7.58.0 in the FTP URL handling that allows an attacker to cause a denial of service or worse.

Affected: NuGet: curl

curl can be coerced into writing a zero byte out of bounds.

This bug can trigger when curl is told to work on an FTP URL, with the setting to only issue a single CWD command (--ftp-method singlecwd or the libcurl alternative [CURLOPT_FTP_FILEMETHOD](https://curl.se/libcurl/c/CURLOPT_FTP_FILEMETHOD.html)).

curl then URL-decodes the given path, calls strlen() on the result and deducts the length of the file name part to find the end of the directory within the buffer. It then writes a zero byte on that index, in a buffer allocated on the heap.

If the directory part of the URL contains a `%00` sequence, the directory length might end up shorter than the file name path, making the calculation `size_t index = directory_len - filepart_len` end up with a huge index variable for where the zero byte gets stored: `heap_buffer[index] = 0`. On several architectures that huge index will wrap and work as a negative value, thus overwriting memory before the intended heap buffer.

By using different file part lengths and putting the string `%00` in different places in the URL, an attacker that can control what paths a curl-using application uses can write that zero byte on different indexes.

A remote attacker can exploit a server 's private key by sending carefully constructed UserIdentityTokens encrypted with the Basic128Rsa15 security policy. This could allow an attacker to decrypt passwords even if encrypted with another security policy such as Basic256Sha256. CVE-2018-7559 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:L). An attacker with physical access to the device can manipulate SD card data, which could allow an attacker to bypass the authentication of the device. This device is designed for use in a protected industrial environment with restricted physical access.CVE-2019-10998 has been assigned to this vulnerability. A CVSS v3 base score of 6.8 has been calculated; the CVSS vector string is (AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). An attacker trying to connect to the device using a man-in-the-middle setup may crash the PLC service, resulting in a denial of service condition. The device must then be rebooted, or the PLC service must be restarted manually via Linux shell.CVE-2019-10997 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). 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 ha…
