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 ========== [ 1 ] CVE-2007-4091 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4091 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200709-13.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
