Synopsis
========
Two user-assisted buffer overflow vulnerabilities have been discovered
in rsync.
Background
==========
rsync is a file transfer program to keep remote directories
synchronized.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/rsync < 2.6.9-r3 >= 2.6.9-r3
Description
===========
Sebastian Krahmer from the SUSE Security Team discovered two off-by-one
errors in the function "f_name()" in file sender.c when processing
overly long directory names.
Impact
======
A remote attacker could entice a user to synchronize a repository
containing specially crafted directories, leading to the execution of
arbitrary code with the privileges of the user running the application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All rsync users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/rsync-2.6.9-r3"
References
==========
