curl: Telnet Suboption Buffer Pointer Underflow in lib/telnet.c leads to Out-of-Bounds Read

Summary A buffer pointer underflow vulnerability exists in curl's telnet protocol handler lib/telnet.c. When processing telnet suboptions in the CURLTSSE state, the code unconditionally decrements the suboption buffer pointer by 2 subpointer -= 2, even when the CURLSBACCUM macro skips writing due...
