Severity: Low Title: OpenLDAP: Insecure usage of /tmp during installation Date: January 23, 2007 Bugs: #159508 ID: 200701-19
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis ========
A shell script commonly released with OpenLDAP makes insecure usage of files in /tmp during the emerge process.
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 a directory 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:
http://security.gentoo.org/glsa/glsa-200701-19.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. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
