Detail
Problem Description: Updated curl packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: 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 libcurl could incorrectly reuse existing connections for requests that should have used different or no authentication credentials, when using one of the following protocols: HTTP(S) with NTLM authentication, LDAP(S), SCP, or SFTP. If an application using the libcurl library connected to a remote server with certain authentication credentials, this flaw could cause other requests to use those same credentials. (CVE-2014-0015, CVE-2014-0138) Red Hat would like to thank the cURL project for reporting these issues. Upstream acknowledges Paras Sethia as the original reporter of CVE-2014-0015 and Yehezkel Horowitz for discovering the security impact of this issue, and Steve Holme as the original reporter of CVE-2014-0138. This update also fixes the following bugs: * Previously, the libcurl library was closing a network socket without first terminating the SSL connection using the socket. This resulted in a write after close and consequent leakage of memory dynamically allocated by the SSL library. An upstream patch has been applied on libcurl to fix this bug. As a result, the write after close no longer happens, and the SSL library no longer leaks memory. (BZ#1092479) * Previously, the libcurl library did not implement a non-blocking SSL handshake, which negatively affected performance of applications based on libcurl's multi API. To fix this bug, the non-blocking SSL handshake has been implemented by libcurl. With this update, libcurl's multi API immediately returns the control back to the application whenever it cannot read/write data from/to the underlying network socket. (BZ#1092480) * Previously, the curl package could not be rebuilt from sources due to an expired cookie in the upstream test-suite, which runs during the build. An upstream patch has been applied to postpone the expiration date of the cookie, which makes it possible to rebuild the package from sources again. (BZ#1092486) * Previously, the libcurl library attempted to authenticate using Kerberos whenever such an authentication method was offered by the server. This caused problems when the server offered multiple authentication methods and Kerberos was not the selected one. An upstream patch has been applied on libcurl to fix this bug. Now libcurl no longer uses Kerberos authentication if another authentication method is selected. (BZ#1096797) All curl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running applications that use libcurl have to be restarted for this update to take effect. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1053903 - CVE-2014-0015 curl: re-use of wrong HTTP NTLM connection in libcurl 1079148 - CVE-2014-0138 curl: wrong re-use of connections in libcurl 1092486 - problem with building curl package 1096797 - RHEL-6 libcurl fails when using digest auth and have multiple auth options |
