Details

Several buffer overflows have been discovered in libxml's FTP
connection and DNS resolution functions. Supplying very long FTP URLs
or IP addresses might result in execution of arbitrary code with the
privileges of the process using libxml.

This does not affect the core XML parsing code, which is what the
majority of programs use this library for.

Note: The same vulnerability was already fixed for libxml2 in
USN-10-1.
