Exim supports the use of multiple "-p" command line arguments which are malloc()'ed and never free()'ed, used in conjunction with other issues allows attackers to cause arbitrary code execution. This affects exim version 4.89 and earlier. Please note that at this time upstream has released a patch (commit 65e061b76867a9ea7aeeb535341b790b90ae6c21), but it is not known if a new point release is available that addresses this issue at this time. Exim es compatible con el uso de múltiples argumentos de líneas de comandos \"-p\" en los que se emplea la función malloc() y nunca la función free(). Estos argumentos, junto con otros problemas permite que los atacantes provoquen la ejecución de código arbitrario. • http://www.debian.org/security/2017/dsa-3888 http://www.securityfocus.com/bid/99252 http://www.securitytracker.com/id/1038779 https://access.redhat.com/security/cve/CVE-2017-1000369 https://github.com/Exim/exim/commit/65e061b76867a9ea7aeeb535341b790b90ae6c21 https://security.gentoo.org/glsa/201709-19 https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt • CWE-404: Improper Resource Shutdown or Release •
