RHSA-2010:0329: Moderate: curl security update

First published: Tue Mar 30 2010(Updated: )

cURL is a tool for getting files from FTP, HTTP, Gopher, Telnet, and DICT<br>servers, using any of the supported protocols. cURL is designed to work<br>without user interaction or any kind of interactivity.<br>Wesley Miaw discovered that when deflate compression was used, libcurl<br>could call the registered write callback function with data exceeding the<br>documented limit. A malicious server could use this flaw to crash an<br>application using libcurl or, potentially, execute arbitrary code. Note:<br>This issue only affected applications using libcurl that rely on the<br>documented data size limit, and that copy the data to the insufficiently<br>sized buffer. (CVE-2010-0734)<br>Users of curl should upgrade to these updated packages, which contain a<br>backported patch to correct this issue. All running applications using<br>libcurl must be restarted for the update to take effect.
