Red Hat RHSA-2013:0983 Moderate: Curl Buffer Overflow Security Update

red hat
Calendar Grey June 25, 2013
Scroller Redhat
The most recent Red Hat notification regarding curl highlights a moderate risk buffer overflow vulnerability. Ensure your systems are updated promptly.
Updated curl packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6

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/articles/11258

Summary

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.
