Debian DSA-106-2 : rsync - remote exploit

critical Nessus Plugin ID 14943

Synopsis

The remote Debian host is missing a security-related update.

Description

Sebastian Krahmer found several places in rsync (a popular tool to synchronise files between machines) where signed and unsigned numbers were mixed which resulted in insecure code (see securityfocus.com).
 This could be abused by remote users to write 0-bytes in rsync's memory and trick rsync into executing arbitrary code.

Solution

This has been fixed in version 2.3.2-1.3 and we recommend you upgrade your rsync package immediately.

Unfortunately the patch used to fix that problem broke rsync. This has been fixed in version 2.3.2-1.5 and we recommend you upgrade to that version immediately.
