Description:
Some vulnerabilities have been reported in pdnsd, which can be exploited by malicious people to poison the DNS cache and cause a DoS (Denial of Service).
1) A vulnerability is caused due to pdnsd not sufficiently randomising the query port number, which can be exploited to poison the DNS cache.
2) An error exists within the "p_exec_query()" function in src/dns_query.c when processing long replies with many answer sections. This can be exploited to e.g. crash the service by sending a specially crafted reply.
The vulnerabilities are reported in versions prior to version 1.2.7-par.
