Title: OpenLDAP: Insecure usage of /tmp during installation (GLSA 200701-19)
Date: January 23, 2007
Updated: March 11, 2007
A shell script commonly released with OpenLDAP makes insecure usage of files in /tmp during the emerge process.
OpenLDAP Software is an open source implementation of the Lightweight Directory Access Protocol.
Vulnerable: < 2.1.30-r10
Vulnerable: < 2.2.28-r7
Vulnerable: < 2.3.30-r2
Unaffected: >= 2.1.30-r10
Unaffected: >= 2.2.28-r7
Unaffected: >= 2.3.30-r2
Architectures: All supported architectures
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.
A local attacker could create a symbolic link in /tmp and potentially overwrite arbitrary system files upon a privileged user emerging OpenLDAP.
There is no known workaround at this time.
All OpenLDAP users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose "net-nds/openldap"
