"Integer signedness error in the simplestring_addn function in
simplestring.c in xmlrpc-epi through 0.54.2 allows remote attackers to
cause a denial of service (heap-based buffer overflow) or possibly
have unspecified other impact via a long first argument to the PHP
xmlrpc_encode_request function.

For Debian 7 'Wheezy', these problems have been fixed in version
0.54.2-1+deb7u1.

We recommend that you upgrade your xmlrpc-epi 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."
