Moderate: curl security update
Security Advisory: Moderate
Updated curl packages that fix one security issue are now available for Red
Hat Enterprise Linux 3 and 4.
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 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.
Wesley Miaw discovered that when deflate compression was used, libcurl
could call the registered write callback function with data exceeding the
documented limit. A malicious server could use this flaw to crash an
application using libcurl or, potentially, execute arbitrary code. Note:
This issue only affected applications using libcurl that rely on the
documented data size limit, and that copy the data to the insufficiently
sized buffer. (CVE-2010-0734)
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.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
