Debian: 'rsync' Remote command execution Print E-mail
User Rating:      How can I rate this item?
Posted by LinuxSecurity.com Team   
Debian There exist several signedness bugs within the rsync program which allow remote attackers to write 0-bytes to almost arbitrary stack-locations, therefore being able to control the programflow and obtaining a shell remotely.

Debian Security Advisory DSA-106-1                   security@debian.org

Package        : rsync
Problem type   : remote exploit
Debian-specific: no

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. This could be abused by
remote users to write 0-bytes in rsync's memory and trick rsync into
executing arbitrary code.

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

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.


Debian GNU/Linux 2.2 alias potato
