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.
For Debian 7 ‘Wheezy’, these problems have been fixed in version 4.80-7+deb7u5.
We recommend that you upgrade your exim4 packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
