RHSA-2005:875 - Security Advisory

Topic

Updated curl packages that fix a security issue are now available for Red
Hat Enterprise Linux 4.

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

Description

cURL is a tool for getting files from FTP, HTTP, Gopher, Telnet, and Dict
servers, using any of the supported protocols.

Stefan Esser discovered an off-by-one bug in curl. It may be possible to
execute arbitrary code on a user's machine if the user can be tricked into
executing curl with a carefully crafted URL. The Common Vulnerabilities and
Exposures project assigned the name CVE-2005-4077 to this issue.

All users of curl are advised to upgrade to these updated packages, which
contain a backported patch that resolves this issue.
