(rsync: Execution of arbitrary code)
Sebastian Krahmer of SUSE reported an integer overflow in the
expand_item_list() function in the file util.c which might lead to a
heap-based buffer overflow when extended attribute (xattr) support is
A remote attacker could send a file containing specially crafted
extended attributes to an rsync deamon, or entice a user to sync from
an rsync server containing specially crafted files, possibly leading to
the execution of arbitrary code.
Please note that extended attributes are only enabled when USE='acl' is
enabled, which is the default setting.
Disable extended attributes in the rsync daemon by setting 'refuse
options = xattrs' in the file '/etc/rsyncd.conf' (or append
'xattrs' to an existing 'refuse' statement). When synchronizing to a
server, do not provide the '-X' parameter to rsync. You can also
disable the 'acl' USE flag for rsync and recompile the package.
