Vulnerability Assessment Details

[GLSA-200510-19] cURL: NTLM username stack overflow

Vulnerability Assessment Summary
cURL: NTLM username stack overflow

Detailed Explanation for this Vulnerability Assessment
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.
