The cURL project reports:

+
FTP PWD response parser out of bounds read
+
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.
