USN-500-1: rsync vulnerability
20 August 2007
rsync vulnerability
Releases
Details
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.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 7.04
-
rsync
-
2.6.9-3ubuntu1.1
Ubuntu 6.10
-
rsync
-
2.6.8-2ubuntu3.1
Ubuntu 6.06
-
rsync
-
2.6.6-1ubuntu2.1
In general, a standard system upgrade is sufficient to effect the
necessary changes.
