GLSA-200709-13 : rsync: Two buffer overflows

medium Nessus Plugin ID 26103

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200709-13 (rsync: Two buffer overflows)

 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.

Solution

All rsync users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/rsync-2.6.9-r3'
