"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has curl packages installed that are affected by a
vulnerability:
- 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 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 almost identical to
CVE-2017-8816.) (CVE-2018-14618)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
