DESCRIPTION:
A vulnerability has been reported in libpam-pgsql, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
potentially compromise a vulnerable system.

The vulnerability is caused due to the "pg_execParam()" function in
src/backend_pgsql.c using an incorrect format specifier, which can be
exploited to cause a heap-based buffer overflow by e.g. connecting
from an IPv4 address containing an octet larger than 127 to an
application using the module.

The vulnerability is reported in version 0.7.1. Other versions may
also be affected.

SOLUTION:
Do not use a vulnerable version of the module.
