CVE-2017-1000257

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 mag...

Heap overflow

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...

CVE-2017-1000099

When asking to get a file from a file:// URL, libcurl provides a feature that outputs meta-data about the file using HTTP-like headers. The code doing this would send the wrong buffer to the user stdout or the application's provide callback, which could lead to other private data from the heap to...

CVE-2017-1000100

When doing a TFTP transfer and curl/libcurl is given a URL that contains a very long file name longer than about 515 bytes, the file name is truncated to fit within the buffer boundaries, but the buffer size is still wrongly updated to use the untruncated length. This too large value is then used...
