In the encoding section of the PROTOS LDAPv3 test suite, these products had an indeterminate number of failures in the group that tests invalid BER length of length fields. In the application section of the PROTOS LDAPv3 test suite, these products failed four groups and had inconclusive results for an additional five groups. The four failed groups indicate the presence of buffer overflow vulnerabilities. For the inconclusive groups, the product exhibited suspicious behavior while testing for format string vulnerabilities. Please read the CERT advisory and info on the PROTOS LDAPv3 test suite at: http://www.ee.oulu.fi/research/ouspg/protos/testing/c06/ldapv3/ SGI has investigated the issue and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL vulnerable SGI systems. - -------------- - --- Impact --- - -------------- SGI sold IRIX Netscape Directory Server versions 1.0, 1.02, 3.0, 3.11, and 4.1. All of those versions are subject to the vulnerabilities outlined in this bulletin. None of these products are currently available from SGI, and all have been retired and are no longer supported by SGI. One or more of these vulnerabilities allow a remote attacker to execute arbitrary code with the privileges of the Directory Server. The server typically runs with root privileges. At least one of these vulnerabilities has been successfully exploited in a laboratory environment under Windows NT 4.0, but they may affect other platforms as well. A local user account on the vulnerable system is not required in order to exploit these vulnerabilities. CERT/CC reported the vulnerabilities: http://www.cert.org/advisories/CA-2001-18.html These vulnerabilities have been publicly discussed in Usenet newsgroups and security mailing lists. - ---------------- - --- Solution --- - ---------------- These products have been retired, and SGI will not be providing a patch for these vulnerabilities. SGI's recommendation is to uninstall the product.
