curl security problems:

+
CVE-2018-16839: SASL password overflow via integer overflow
+
libcurl contains a buffer overrun in the SASL authentication code.
+
The internal function Curl_auth_create_plain_message fails to + correctly verify that the passed in lengths for name and password + aren't too long, then calculates a buffer size to allocate.
+
On systems with a 32 bit size_t, the math to calculate the buffer size + triggers an integer overflow when the user name length exceeds 2GB + (2^31 bytes). This integer overflow usually causes a very small buffer + to actually get allocated instead of the intended very huge one, making + the use of that buffer end up in a heap buffer overflow.
+
This bug is very similar to CVE-2017-14618.
+
It affects curl 7.33.0 to 7.61.1.
+
CVE-2018-16840: use-after-free in handle close
+
libcurl contains a heap use-after-free flaw in 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.
+
It affects curl 7.59.0 to 7.61.1.
+
CVE-2018-16842: warning message out-of-buffer read
+
curl contains a heap out of buffer read vulnerability.
+
The command line tool has a generic function for displaying warning + and informational messages to stderr for various situations. For + example if an unknown command line argument is used, or passed to it in + a "config" file.
+
This display function formats the output to wrap at 80 columns. The + wrap logic is however flawed, so if a single word in the message is + itself longer than 80 bytes the buffer arithmetic calculates the + remainder wrong and will end up reading behind the end of the buffer. + This could lead to information disclosure or crash.
+
This vulnerability could lead to a security issue if used in this or + similar situations:
+
1. a server somewhere uses the curl command line to run something
+
2. if it fails, it shows stderr to the user
+
3. the server takes user input for parts of its command line input
+
4. user provides something overly long that triggers this crash
+
5. the stderr output may now contain user memory contents that wasn't + meant to be available
+
It affects curl 7.14.1 to 7.61.1.
