Background ========= OpenLDAP Software is an open source implementation of the Lightweight Directory Access Protocol. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-nds/openldap < 2.1.30-r10 > = 2.1.30-r10 > = 2.2.28-r7 > = 2.3.30-r2 net-nds/openldap < 2.2.28-r7 > = 2.1.30-r10 > = 2.2.28-r7 > = 2.3.30-r2 net-nds/openldap < 2.3.30-r2 > = 2.1.30-r10 > = 2.2.28-r7 > = 2.3.30-r2 Description ========== Tavis Ormandy of the Gentoo Linux Security Team has discovered that the file gencert.sh distributed with the Gentoo ebuild for OpenLDAP does not exit upon the existence of adirectory in /tmp during installation allowing for directory traversal. Impact ===== A local attacker could create a symbolic link in /tmp and potentially overwrite arbitrary system files upon a privileged user emerging OpenLDAP. Workaround ========= There is no known workaround at this time. Resolution ========= All OpenLDAP users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "net-nds/openldap" Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200701-19 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.
