CVSS: 4.3EPSS: 8%CPEs: 14EXPL: 0CVE-2010-0433 – openssl: crash caused by a missing krb5_sname_to_principal() return value check
https://notcve.org/view.php?id=CVE-2010-0433
The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL before 0.9.8n, when Kerberos is enabled but Kerberos configuration files cannot be opened, does not check a certain return value, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via SSL cipher negotiation, as demonstrated by a chroot installation of Dovecot or stunnel without Kerberos configuration files inside the chroot. La funcion kssl_keytab_is_available en ssl/kssl.c en OpenSSL before v0.9.8n, cuando Kerberos esta activo pero los ficheros de configuracion de Kerberos no pueden ser abiertos, no comprueba adecuadamente cierto valor de retorno, lo que permite a atacantes remotos producir una denegacion de servicio (desreferencia a puntero nulo y caida de demonio) a traves de la negociacion del cifrado SSL, lo que se demuestra mediante la instalacion chroot de Dovecot o stunnel sin los ficheros de configuracion de Kerberos dentro de chroot. • http://aix.software.ibm.com/aix/efixes/security/openssl_advisory.asc http://cvs.openssl.org/chngview?cn=19374 http://groups.google.com/group/mailing.openssl.users/browse_thread/thread/c3e1ab0034ca4b4c/66aa896c3a78b2f7 http://lists.fedoraproject.org/pipermail/package-announce/2010-April/038587.html http://lists.fedoraproject.org/pipermail/package-announce/2010-April/039561.html http://marc.info/?l=bugtraq&m=127128920008563&w=2 http://marc.info/?l=bugtraq&m=127557640302499&w=2 http://secunia.com& • CWE-20: Improper Input Validation •

OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain signature calculations, and does not verify the signature before providing it to a caller, which makes it easier for physically proximate attackers to determine the private key via a modified supply voltage for the microprocessor, related to a "fault-based attack." OpenSSL 0.9.8i en Gaisler Research LEON3 SoC sobre Xilinx Virtex-II Pro FPGA utiliza un algoritmo Fixed Width Exponentiation (FWE) para ciertos calculos de firma, el cual no verifica previamente la firma del cliente, lo que hace que atacantes proximos fisicamente puedan determinar la clave privada a traves de una modificacion del voltaje del microprocesador, relacionado con el ataque "fault-based attack." • http://rdist.root.org/2010/03/08/attacking-rsa-exponentiation-with-fault-injection http://www.eecs.umich.edu/~valeria/research/publications/DATE10RSA.pdf http://www.networkworld.com/news/2010/030410-rsa-security-attack.html http://www.osvdb.org/62808 http://www.theregister.co.uk/2010/03/04/severe_openssl_vulnerability https://exchange.xforce.ibmcloud.com/vulnerabilities/56750 • CWE-310: Cryptographic Issues •

The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. El protocolo TLS y el protocolo SSL v3.0 y posiblemente versiones anteriores, tal y como se usa en Microsoft Internet Information Services (IIS) v7.0, mod_ssl en el servidor HTTP Apache v2.2.14 y anteriores, OpenSSL antes de v0.9.8l, GnuTLS v2.8.5 y anteriores, Mozilla Network Security Services (NSS) v3.12.4 y anteriores, y otros productos, no asocia apropiadamente la renegociación del Handshake SSL en una conexión existente, lo que permite ataques man-in-the-middle en los que el atacante inserta datos en sesiones HTTPS, y posiblemente otro tipo de sesiones protegidas por SSL o TLS, enviando una petición de autenticación que es procesada retroactivamente por un servidor en un contexto post-renegociación.
