Problem description

This update addresses two different vulnerabilities in the openssl library that can be used by an attacker to crash the program that makes use of the openssl routines and functions.
The first vulnerability is known as "NULL pointer during SSL handshake (CAN-2004-0079)" - an attacker can cause the openssl library to crash upon reception of a carefully crafted packet from the attacker. This may result in a Denial of Service attack, depending on the application that makes use of the openssl functions.
The second vulnerability affects Kerberos Ciphersuites, identified as CAN-2004-0112. A remote attacker can run an attack against a server that is configured to use Kerberos Ciphersuites. The attack can result in a crash within the openssl library during SSL/TLS handshake. Most applications that link against openssl are unaffected because they do not make use of the Kerberos Ciphersuites.
The two vulnerabilites that are subject to this update have been discovered by
CAN-2004-0079:
  • The openssl project while performing testing against the TLS test suite developed by Codenomicon, and in cooperation with the NISCC.
CAN-2004-0112:
  • Stephen Henson.
Note: This update refers to the openssl-devel package. While the "openssl" package contains the runtime linkable libraries (aka shared libraries, DLLs), the openssl-devel package contains statically linkable libraries. If you are using programs that have statically linked the openssl library, you should consider recompiling these programs after this update has installed correctly and completely. Other than recompiling (and re-linking) programs, the update of the openssl-devel package will have no effect on your running system.
