Background ========== cURL is a command line tool for transferring files with URL syntax, supporting numerous protocols. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/curl < 7.19.4 >= 7.19.4 Description =========== David Kierznowski reported that the redirect implementation accepts arbitrary Location values when CURLOPT_FOLLOWLOCATION is enabled. Impact ====== A remote attacker could possibly exploit this vulnerability to make remote HTTP servers trigger arbitrary requests to intranet servers and read or overwrite arbitrary files via a redirect to a file: URL, or, if the libssh2 USE flag is enabled, execute arbitrary commands via a redirect to an scp: URL. Workaround ========== There is no known workaround at this time. Resolution ========== All cURL users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/curl-7.19.4" References ========== [ 1 ] CVE-2009-0037 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0037 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200903-21.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
