CVE-2019-17266: libsoup: heap-based over-read in soup_ntlm_parse_challenge() in soup-auth-ntlm.c

Severity: Critical

CVSS Score: 9.8

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.
