DESCRIPTION:
A vulnerability has been reported in rsync, which can be exploited by
malicious users to cause a DoS (Denial of Service) and potentially
compromise a vulnerable system.

The vulnerability is caused due to an integer overflow error in the
"receive_xattr()" function within the xattrs.diff patch. This can be
exploited to cause a buffer overflow and may allow arbitrary code
execution via specially crafted extended attributes.

Successful exploitation requires that the "xattrs.diff" patch has
been applied.

The vulnerability has been reported in version 2.6.7. Prior versions
may also be affected.
