A local overflow exists in Conquest. In conf.c and conqlb.c there are several sprintf calls that read data from the HOME variable without checking the length resulting in a buffer overflow. With a specially crafted request, an attacker can execute arbitrary code as the group that owns the conquest executable (conquest is installed SGID) resulting in a loss of integrity, and/or availability.
