RHEL 4 / 5 / 6 : curl (RHSA-2011:0918)

critical Nessus Plugin ID 55519

Language:

Synopsis

The remote Red Hat host is missing a security update for curl.

Description

The remote Redhat Enterprise Linux 4 / 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:0918 advisory.

cURL provides the libcurl library and a command line tool for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.

It was found that cURL always performed credential delegation when authenticating with GSSAPI. A rogue server could use this flaw to obtain the client's credentials and impersonate that client to other servers that are using GSSAPI. (CVE-2011-2192)

Users of curl should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using libcurl must be restarted for the update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL curl package based on the guidance in RHSA-2011:0918.
