{"vuid":"VU#481564","idnumber":"481564","name":"Kerberos administration daemon fails to properly initialize function pointers","keywords":["Kerberos","administration daemon","kadmind","arbitrary code execution","RPC library","apple_2007-004"],"overview":"The Kerberos administration daemon fails to properly initialize pointers. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code or cause a denial of service.","clean_desc":"A vulnerability exists in the way the Kerberos administration daemon handles pointers that may allow a remote, unauthenticated user to execute arbitrary code. According to MIT krb5 Security Advisory 2006-002: The Kerberos administration daemon, \"kadmind\", can execute arbitrary code by calling through a function pointer located in freed memory. This vulnerability results from bugs in the server-side portion of the RPC library. Note that krb5-1.4 through krb5-1.4.4, and krb5-1.5 through krb5-1.5.1 are affected by this vulnerability. Other server applications that utilize the RPC library provided with MIT krb5 may also be affected. This vulnerability can be triggered by sending a specially crafted Kerberos packet to a vulnerable system.","impact":"A remote, unauthenticated user may be able to execute arbitrary code resulting in the compromise of the Kerberos key database or cause a denial of service.","resolution":"Apply Patch A patch can be obtained from MIT krb5 Security Advisory 2006-002. MIT also states that this will be addressed in the upcoming krb5-1.6 release and krb5-1.5.2 patch release.","workarounds":"","sysaffected":"","thanks":"This issue is addressed in \nMIT krb5 Security Advisory \n2006-002\n.
