ClamAV clamav-milter code execution
|clamav-clamavmilter-code-execution (36263)||High Risk|
Clam AntiVirus (ClamAV) could allow a remote attacker to execute arbitrary code on the system, caused by improper validation of recipient addresses extracted from email messages when using sendmail. If the clamav-milter is started with the "black hole" mode activated, a remote attacker could send a specially-crafted email with a malicious recipient address in a popen() function call to inject shell commands and execute arbitrary code on the system with root privileges.
