Hypermail CGI Mail Reverse DNS Lookup Buffer Overflow Vulnerability
A buffer overflow vulnerability has been reported for Hypermail's CGI mail program. The vulnerability exists due to insufficient bounds checking performed by the CGI mail program when resolving DNS replies. Operators of malicious DNS servers may exploit this condition to execute arbitrary code on target hosts. It may also be possible for attackers who do not control the DNS server to spoof malicious responses. |
