Descriptions
Postfix 2.4 before 2.4.9, 2.5 before 2.5.5, and 2.6 before 2.6-20080902, when used with the Linux 2.6 kernel, leaks epoll file descriptors during execution of "non-Postfix" commands, which allows local users to cause a denial of service (application slowdown or exit) via a crafted command, as demonstrated by a command in a .forward file.
Postfix versión 2.4 anteriores a la 2.4.9, versión 2.5 anteriores a la 2.5.5 y versión 2.6 anteriores a la 2.6-2000902, cuando se utiliza con el nucleo de Linux versión 2.6, muestra los descriptores del fichero epoll durante la ejecución de comandos que no son Postfix, permite a usuarios locales provocar una denegación de servicio (aplicación más lenta o finalización) mediante un comando especialmente construido, como se ha demostrado por un comando en un fichero .forward.
A memory leak in Postfix might allow local users to cause a Denial of Service. It has been discovered than Postfix leaks an epoll file descriptor when executing external commands, e.g. user-controlled $HOME/.forward or $HOME/.procmailrc files. NOTE: This vulnerability only concerns Postfix instances running on Linux 2.6 kernels. Versions less than 2.4.9 are affected.
