cURL/libcURL GSS/Negotiate Feature Spoofing Security Vulnerability



The cURL program is a library and command-line tool for transferring data using various protocols, including HTTP, FTP, and LDAP. A vulnerable version of cURL was detected from the host.


It was reported that the application always performs credential delegation when authenticating with GSSAPI. A rouge 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)

Affected versions include versions 7.10.6 through 7.21.6.


Upgrade the affected packages; the next version of cURL that fixes the issue is cURL 7.21.7.
