RHEL 6 : curl (Unpatched Vulnerability)

critical Nessus Plugin ID 198460

Synopsis

The remote Red Hat 6 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

- curl: NTLM password overflow via integer overflow (CVE-2018-14618)

- The default configuration for cURL and libcurl before 7.42.1 sends custom HTTP headers to both the proxy and destination server, which might allow remote proxy servers to obtain sensitive information by reading the header contents. (CVE-2015-3153)

- The ConnectionExists function in lib/url.c in libcurl before 7.47.0 does not properly re-use NTLM- authenticated proxy connections, which might allow remote attackers to authenticate as other users via a request, a similar issue to CVE-2014-0015. (CVE-2016-0755)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
