| Description: |
The remote host is missing an update to rsync
announced via advisory USN-500-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Details follow:
Sebastian Krahmer discovered that rsync contained an off-by-one
miscalculation when handling certain file paths. By creating a specially
crafted tree of files and tricking an rsync server into processing them,
a remote attacker could write a single NULL to stack memory, possibly
leading to arbitrary code execution.
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
rsync 2.6.6-1ubuntu2.1
Ubuntu 6.10:
rsync 2.6.8-2ubuntu3.1
Ubuntu 7.04:
rsync 2.6.9-3ubuntu1.1
In general, a standard system upgrade is sufficient to effect the
necessary changes.
