Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Andreas Seltenreich reports that hashcash is prone to a heap overflow
vulnerability. This vulnerability is caused by improper checking of
memory allocations within the 'array_push()' function. An attacker
could trigger this vulnerability by passing a lot of '-r' or '-j'
flags from the command line, this only applies when the application is
configured to allow command line options, or by passing a lot of
resource names when the application was started with the '-m' flag
set. This could lead to a Denial or Service or could allow remote
access to the targeted system.
