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)
All running applications using libcurl must be restarted for the update
to take effect.
