Red Hat: 2011:0390-01: rsync: Moderate Advisory
Summary
rsync is a program for synchronizing files over a network.
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)
Red Hat would like to thank Wayne Davison and Matt McCutchen for reporting
this issue.
Users of rsync should upgrade to this updated package, which contains a
backported patch to resolve this issue.
