Detail

Problem Description:

Updated curl packages that fix security issues are now available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

cURL is a tool for getting files from FTP, HTTP, Gopher, Telnet, and Dict servers, using any of the supported protocols. cURL is designed to work without user interaction or any kind of interactivity.

Scott Cantor reported that cURL is affected by the previously published "null prefix attack", caused by incorrect handling of NULL characters in X.509 certificates. If an attacker is able to get a carefully-crafted certificate signed by a trusted Certificate Authority, the attacker could use the certificate during a man-in-the-middle attack and potentially confuse cURL into accepting it by mistake. (CVE-2009-2417)

cURL users should upgrade to these updated packages, which contain a backported patch to correct these issues. All running applications using libcurl must be restarted for the update to take effect.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

Title: VMware curl vulnerability
Description: lib/ssluse.c in cURL and libcurl 7.4 through 7.19.5, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

Description: It was discovered that curl, a client and library to get files from servers using HTTP, HTTPS or FTP, is vulnerable to the "Null Prefix Attacks Against SSL/TLS Certificates" recently published at the Blackhat conference. This allows an attacker to perform undetected man-in-the-middle attacks via a crafted ITU-T X.509 certificate with an injected null byte in the Common Name field.

This allows an attacker to perform undetected man-in-the-middle attacks via a crafted ITU-T X.509 certificate with an injected null byte in the Common Name field. For the oldstable distribution, this problem has been fixed in version 7.15.5-1etch3. For the stable distribution, this problem has been fixed in version 7.18.2-8lenny3. For the testing and unstable distribution, this problem will be fixed soon. We recommend that you upgrade your curl packages.

Title: USN-1158-1 -- curl vulnerabilities
Description: curl: HTTP, HTTPS, and FTP client and client libraries Details: Richard Silverman discovered that when doing GSSAPI authentication, libcurl unconditionally performs credential delegation, handing the server a copy of the client�s security credential. Wesley Miaw discovered that when zlib is enabled, libcurl does not properly restrict the amount of callback data sent to an application that requests automatic decompression. This might allow an attacker to cause a denial of service via an application crash or possibly execute arbitrary code with the privilege of the application. This issue only affected Ubuntu 8.04 LTS and Ubuntu 10.04 LTS. USN 818-1 fixed an issue with curl�s handling of SSL certificates with zero bytes in the Common Name. Due to a packaging error, the fix for this issue was not being applied during the build. This issue only affected Ubuntu 8.04 LTS. We apologize for the error. Original advisory Multiple vulnerabilities in curl.
