Description
From CVE.org
The smb_request_state function in cURL and libcurl 7.40.0 through 7.42.1 allows remote SMB servers to obtain sensitive information from memory or cause a denial of service (out-of-bounds read and crash) via crafted length and offset values.
Statement
This issue did not affect the versions of curl as shipped with Red Hat Enterprise Linux 5, 6, and 7, as they did not include support for SMB/CIFS.
