CVSS: 10.0EPSS: 96%CPEs: 12EXPL: 0CVE-2007-3999 – Multiple Kerberos Implementations Authentication Context Stack Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2007-3999
Stack-based buffer overflow in the svcauth_gss_validate function in lib/rpc/svc_auth_gss.c in the RPCSEC_GSS RPC library (librpcsecgss) in MIT Kerberos 5 (krb5) 1.4 through 1.6.2, as used by the Kerberos administration daemon (kadmind) and some third-party applications that use krb5, allows remote attackers to cause a denial of service (daemon crash) and probably execute arbitrary code via a long string in an RPC message. Un desbordamiento de búfer en la región stack de la memoria en la función svcauth_gss_validate en el archivo lib/rpc/svc_auth_gss.c en la biblioteca RPCSEC_GSS RPC (librpcsecgss) en MIT Kerberos 5 (krb5) versiones 1.4 hasta 1.6.2, como es usado por demonio de administración de Kerberos (kadmind) y algunas aplicaciones de terceros que usan krb5 permiten a atacantes remotos causar una denegación de servicio (bloqueo del demonio) y probablemente ejecutar código arbitrario por medio de una cadena larga en un mensaje RPC. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of MIT Kerberos. Authentication is not required to exploit this vulnerability. The specific flaw exists in the svcauth_gss_validate() function. By sending a large authentication context over RPC, a stack based buffer overflow occurs, resulting in a situation allowing for remote code execution. The vulnerable line of the function is: memcpy((caddr_t)buf, oa->oa_base, oa->oa_length); If 128 < oa->oa_length < 400, the exploitable situation occurs. • http://docs.info.apple.com/article.html?artnum=307041 http://lists.apple.com/archives/security-announce/2007/Nov/msg00002.html http://lists.rpath.com/pipermail/security-announce/2007-September/000237.html http://secunia.com/advisories/26676 http://secunia.com/advisories/26680 http://secunia.com/advisories/26684 http://secunia.com/advisories/26691 http://secunia.com/advisories/26697 http://secunia.com/advisories/26699 http://secunia.com/advisories/26700 http://secunia.com/advisories&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The gssrpc__svcauth_gssapi function in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a zero-length RPC credential, which causes kadmind to free an uninitialized pointer during cleanup. La función gssrpc__svcauth_gssapi en la librería RPC de MIT Kerberos 5 (krb5) 1.6.1 y anteriores podría permitir a atacantes remotos ejecutar código de su elección mediante credenciales RPC de longitud cero, lo cual provoca que kadmind libere un puntero no inicializado durante la limpieza. • ftp://patches.sgi.com/support/free/security/advisories/20070602-01-P.asc http://docs.info.apple.com/article.html?artnum=306172 http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02257427 http://lists.apple.com/archives/security-announce//2007/Jul/msg00004.html http://lists.grok.org.uk/pipermail/full-disclosure/2007-September/065902.html http://osvdb.org/36596 http://secunia.com/advisories/25800 http://secunia.com/advisories/25801 http://secunia.com/advisories/258 • CWE-824: Access of Uninitialized Pointer •
