Debian DSA-538-1 : rsync - unsanitised input processing

medium Nessus Plugin ID 15375

Synopsis

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

Description

The rsync developers have discovered a security related problem in rsync, a fast remote file copy program, which offers an attacker to access files outside of the defined directory. To exploit this path-sanitizing bug, rsync has to run in daemon mode with the chroot option being disabled. It does not affect the normal send/receive filenames that specify what files should be transferred. It does affect certain option paths that cause auxiliary files to be read or written.

Solution

Upgrade the rsync package.

For the stable distribution (woody) this problem has been fixed in version 2.5.5-0.6.
