The remote host is affected by the vulnerability described in GLSA-200510-19 (cURL: NTLM username stack overflow)
iDEFENSE reported that insufficient bounds checking on a memcpy() of the supplied NTLM username can result in a stack overflow.
Impact :
A remote attacker could setup a malicious server and entice an user to connect to it using a cURL client, potentially leading to the execution of arbitrary code with the permissions of the user running cURL.
Workaround :
Disable NTLM authentication by not using the --anyauth or --ntlm options when using cURL (the command line version). Workarounds for programs that use the cURL library depend on the configuration options presented by those programs.
