RHSA-2013:0771 - Moderate: curl security update

Synopsis

Moderate: curl security update

Type/Severity

Security Advisory Moderate

Topic

Updated curl packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Description

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

A flaw was found in the way libcurl matched domains associated with cookies. This could lead to cURL or an application linked against libcurl sending the wrong cookie if only part of the domain name matched the domain associated with the cookie, disclosing the cookie to unrelated hosts. (CVE-2013-1944)

Red Hat would like to thank the cURL project for reporting this issue. Upstream acknowledges YAMADA Yasuharu as the original reporter.

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.
