Subject Name: Sendmail Subject Summary: Mail Transfer Agent Subject Home: http://www.sendmail.org/ Subject Versions: * <= 8.12.7 Vulnerability Id: none Vulnerability Scope: global (not OpenPKG specific) Attack Feasibility: run-time Attack Vector: remote network Attack Impact: denial of service Description: Oleg Bulyzhin reported to FreeBSD [1] a confirmed [2] Denial of Service (DoS) vulnerability in all version of the Sendmail MTA [0] earlier than 8.12.9. Due to a wrong initialization of an internal structure, if Sendmail gets a bad DNS reply (with actual reply size not equal the announced reply size), it later calls free() on a random address. This usually cause Sendmail to crash.
