The kadm_ser_in function in (1) the Kerberos v4compatibility administration daemon (kadmind4) in the MIT Kerberos 5 (krb5) krb5-1.2.6 and earlier, (2) kadmind in KTH Kerberos 4 (eBones) before 1.2.1, and (3) kadmind in KTH Kerberos 5 (Heimdal) before 0.5.1 when compiled with Kerberos 4 support, does not properly verify the length field of a request, which allows remote attackers to execute arbitrary code via a buffer overflow attack. La función kadm_ser en el demonio de administración de compatibildad de Kerberos v4 (kadmind4) en el MIT Kerberos 5 (krb5) krb5-1.2.6 y anteriores kadmind en KTH Kerberos 4 (eBones) anteriores a 1.2.1, y kadmind en KTH Kerberos 5 (Heimdal) anteriores a 0.5.1 compilados con soporte de Kerberos 4, no verifica adecuadamente la longitud de un campo de petición, lo que permite a atacantes remotos ejecutar código arbitrario mediante un ataque de desbordamiento de búfer. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2002-026.txt.asc http://archives.neohapsis.com/archives/bugtraq/2002-10/0399.html http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000534 http://marc.info/?l=bugtraq&m=103539530729206&w=2 http://marc.info/?l=bugtraq&m=103564944215101&w=2 http://marc.info/?l=bugtraq&m=103582517126392&w=2 http://marc.info/? •

Buffer overflow in MIT Kerberos 5 (krb5) 1.2.2 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via base-64 encoded data, which is not properly handled when the radix_encode function processes file glob output from the ftpglob function. • http://download.immunix.org/ImmunixOS/7.0/updates/IMNX-2001-70-022-01 http://marc.info/?l=bugtraq&m=98826223517788&w=2 http://web.mit.edu/kerberos/www/advisories/ftpbuf.txt http://www.redhat.com/support/errata/RHSA-2001-060.html https://access.redhat.com/security/cve/CVE-2001-1323 https://bugzilla.redhat.com/show_bug.cgi?id=1616667 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
