+ Exim is an highly configurable message transfer agent (MTA) + developed at the University of Cambridge. +

+
+ +

+ Buffer overflows have been found in the host_aton() function + (CAN-2005-0021) as well as in the spa_base64_to_bits() function + (CAN-2005-0022), which is part of the SPA authentication code. +

+
+ +

+ A local attacker could trigger the buffer overflow in host_aton() + by supplying an illegal IPv6 address with more than 8 components, using + a command line option. The second vulnerability could be remotely + exploited during SPA authentication, if it is enabled on the server. + Both buffer overflows can potentially lead to the execution of + arbitrary code. +

+
+ +

+ There is no known workaround at this time. +

+
+ +

+ All Exim users should upgrade to the latest version: +
