A memory corruption flaw was found in the way the rsync client processed malformed file list data. If an rsync client used the ‘–recursive’ and ‘–delete’ options without the ‘–owner’ option when connecting to a malicious rsync server, the malicious server could cause rsync on the client system to crash or, possibly, execute arbitrary code with the privileges of the user running rsync.
(CVE-2011-1097)
We would like to thank Wayne Davison and Matt McCutchen for reporting this issue.
