The full text of these alerts can be obtained from this mail server by requesting the 'CERT' and 'ERS' files. This information (and more) is available from CERT and ERS directly on the world-wide web at the following URLs: CERT: http://www.cert.org/ ERS: http://www.ers.ibm.com/ In order to keep the size of this file reasonable, it contains only advisories for the current year.. You can obtain a list of previous advisories either from the above URLs, or by requesting one of the "Security_YYYY" documents from this mail server. The fixes mentioned in this document, when available, can be obtained from Electronic Fix Distribution at the following URL: http://techsupport.services.ibm.com/server/fixes The 'Security_APARs' document on this mail server contains a list of security related APARs. =============================================================================== =============================================================================== CERT Advisory CA-2002-15 Denial-of-Service Vulnerability in ISC BIND 9 AIX is not vulnerable. =============================================================================== =============================================================================== CERT Advisory CA-2002-12 Format String Vulnerability in ISC DHCPD AIX is not vulnerable. =============================================================================== =============================================================================== CERT Advisory CA-2002-11 Heap Overflow in Cachefs Daemon (cachefsd) AIX is not vulnerable. =============================================================================== =============================================================================== CERT Advisory CA-2002-10 Format String Vulnerability in rpc.rwalld AIX 4.3 and 5.1 are not vulnerable. =============================================================================== =============================================================================== CERT Advisory CA-2002-07 Double Free Bug in zlib Compression Library (Updated 3/29/2002) IBM's AIX operating system, version 5.1, ships with open source-originated zlib that is used with the Redhat Package Manager (rpm) to install applications that are included in the AIX-Linux Affinity Toolkit. zlib (libz.a) is a shared library in AIX. AIX 5.1 is susceptible to the described vulnerability. AIX 4.3.x does not ship with zlib, but customers who install zlib and use it will be similarly vulnerable. An updated rpm.rte install image for AIX 5.1 can be obtained from: ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/INSTALLP/ppc/ Customers that have installed zlib from the AIX-Linux Affinity Toolkit CD can obtain an updated zlib RPM from: ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/zlib/ =============================================================================== =============================================================================== CERT Advisory CA-2002-06 Vulnerabilities in Various Implementations of the RADIUS Protocol AIX is not vulnerable. =============================================================================== =============================================================================== CERT Advisory CA-2002-03: Multiple Vulnerabilities in Many Implementations of the Simple Network Management Protocol (SNMP) The AIX operating system is susceptible to the vulnerabilities tested for by the Oulu University PROTOS test suite for all levels of AIX 4.3.x prior to level 4.3.3.51, and AIX 5.1 prior to level 5.1.0.10. APARs were developed and made available last year that closed the vulnerabilities looked for by the test suite. For 4.3.x, the relevant APAR is #IY17630; for 5.1, the appropriate APAR is #IY20943. To see if your version and level of AIX is vulnerable, enter the command: lslpp -l bos.net.tcp.client If the "Level" stated is lower than those given above, your system is vulnerable, and you are urged to apply the appropriate APAR. AIX versions prior to 4.3 are also vulnerable, but these versions are no longer supported by IBM. =============================================================================== =============================================================================== - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
