Package: slapd Version: 2.4.31-1+nmu2 Severity: normal The configure script sets the following access rules for the LDAP database:
| olcAccess: to attrs=userPassword,shadowLastChange | by self write | by anonymous auth | by dn="cn=admin,@SUFFIX@" write | by * none | olcAccess: to dn.base="" by * read | olcAccess: to * | by self write | by dn="cn=admin,@SUFFIX@" write | by * read When the LDAP is used to authenticate users (e.g. in conjunction with libnss-ldapd and libpam-ldapd), the rule "olcAccess: to * by self write" allows the user to change her uidNumber and impersonate another user. IMO the default config should allow self-write access to userPassword and shadowLastChange only. If this is not possible, write access should at least be limited to attributes which are commonly expected to be user-writeable, e.g.: | olcAccess: to attrs=userPassword,shadowLastChange | by self write | by anonymous auth | by dn="cn=admin,@SUFFIX@" write | by * none | olcAccess: to attrs=loginShell,gecos | by self write | by dn="cn=admin,@SUFFIX@" write | by * read | olcAccess: to dn.base="" by * read | olcAccess: to * | by dn="cn=admin,@SUFFIX@" write | by * read -- System Information: Debian Release: 7.6 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/1 CPU core) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages slapd depends on: ii adduser 3.113+nmu3 ii coreutils 8.13-3.5 ii debconf [debconf-2.0] 1.5.49 ii libc6 2.13-38+deb7u4 ii libdb5.1 5.1.29-5 ii libgcrypt11 1.5.0-5+deb7u1 ii libgnutls26 2.12.20-8+deb7u2 ii libldap-2.4-2 2.4.31-1+nmu2 ii libltdl7 2.4.2-1.1 ii libodbc1 2.2.14p2-5 ii libperl5.14 5.14.2-21+deb7u1 ii libsasl2-2 2.1.25.dfsg1-6+deb7u1 ii libslp1 1.2.1-9 ii libwrap0 7.6.q-24 ii lsb-base 4.1+Debian8+deb7u1 ii multiarch-support 2.13-38+deb7u4 ii perl [libmime-base64-perl] 5.14.2-21+deb7u1 ii psmisc 22.19-1+deb7u1 Versions of packages slapd recommends: ii libsasl2-modules 2.1.25.dfsg1-6+deb7u1 Versions of packages slapd suggests: ii ldap-utils 2.4.31-1+nmu2 -- Configuration Files: /etc/default/slapd changed [not included] -- debconf information excluded -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
