CVSS: 7.5EPSS: 1%CPEs: 16EXPL: 1CVE-2018-16890 – curl: NTLM type-2 heap out-of-bounds buffer read
https://notcve.org/view.php?id=CVE-2018-16890
06 Feb 2019 — libcurl versions from 7.36.0 to before 7.64.0 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.

06 Feb 2019 — libcurl versions from 7.36.0 to before 7.64.0 are 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 loca... • http://www.securityfocus.com/bid/106950 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

06 Feb 2019 — 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. libcurl, desde la versión 7.34.0 hasta antes de la 7.64.0, es vulnerable a una lectura de memoria dinámica (heap) fuer... • http://www.securityfocus.com/bid/106950 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2018-14618
05 Sep 2018 — curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length excee... • http://www.securitytracker.com/id/1041605 • CWE-122: Heap-based Buffer Overflow CWE-131: Incorrect Calculation of Buffer Size CWE-190: Integer Overflow or Wraparound •
CVSS: 9.1EPSS: 0%CPEs: 6EXPL: 0CVE-2018-1000005 – curl: Out-of-bounds read in code handling HTTP/2 trailers
https://notcve.org/view.php?id=CVE-2018-1000005
24 Jan 2018 — libcurl 7.49.0 to and including 7.57.0 contains an out bounds read in code handling HTTP/2 trailers. It was reported (https://github.com/curl/curl/pull/2231) that reading an HTTP/2 trailer could mess up future trailers since the stored size was one byte less than required. The problem is that the code that creates HTTP/1-like headers from the HTTP/2 trailer data once appended a string like `:` to the target buffer, while this was recently changed to `: ` (a space was added after the colon) but the following... • http://www.securitytracker.com/id/1040273 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2017-1000257
23 Oct 2017 — An IMAP FETCH response line indicates the size of the returned data, in number of bytes. When that response says the data is zero bytes, libcurl would pass on that (non-existing) data with a pointer and the size (zero) to the deliver-data function. libcurl's deliver-data function treats zero as a magic number and invokes strlen() on the data to figure out the length. The strlen() is called on a heap based buffer that might not be zero terminated so libcurl might read beyond the end of it into whatever memor... • http://www.debian.org/security/2017/dsa-4007 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2017-1000254
06 Oct 2017 — 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 ... • http://www.debian.org/security/2017/dsa-3992 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
