CVE-2019-17266
libsoup from versions 2.65.1 until 2.68.1 have a heap-based buffer over-read because soup_ntlm_parse_challenge() in soup-auth-ntlm.c does not properly check an NTLM message's length before proceeding with a memcpy.

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
