RHEL 5 / 6 : curl (RHSA-2013:0983)

medium Nessus Plugin ID 66981

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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.

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

A heap-based buffer overflow flaw was found in the way libcurl unescaped URLs. A remote attacker could provide a specially crafted URL that, when processed by an application using libcurl that handles untrusted URLs, would possibly cause it to crash or, potentially, execute arbitrary code. (CVE-2013-2174)

Red Hat would like to thank the cURL project for reporting this issue.
Upstream acknowledges Timo Sirainen 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.

Solution

Update the affected packages.
