Problem Description A buffer overflow in the DNS SRV code for nss_ldap allows remote attackers to cause a denial of service and possibly execute arbitrary code. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to nss_ldap-172-5.i386.rpm OpenLinux 3.1.1 Workstation prior to nss_ldap-172-5.i386.rpm OpenLinux 3.1 Server prior to nss_ldap-172-5.i386.rpm OpenLinux 3.1 Workstation prior to nss_ldap-172-5.i386.rpm 3. Solution The proper solution is to install the latest packages. Many customers find it easier to use the Caldera System Updater, called cupdate (or kcupdate under the KDE environment), to update these packages rather than downloading and installing them by hand. 4.
