Title: MMMail Remote SysLog Format String Vulnerability
Severity: HIGH
Description:
mmmail is a freely available, open source mail software package. It was written originally by Matthew Mondor, and is available for the Linux operating system.
A problem with mmmail could make it possible for a remote attacker to execute arbitrary code.
Due to improper use of the syslog call, a problem exists which could make the execution of arbitrary code possible. A syslog call in the program which logs user-supplied information could be exploited to print to specified places in memory, including potentially overwriting the return address of a function and executing arbitrary code.
This problem could allow an attacker to send a malicious format string to the syslog function of the program. The malicious format string, and any code supplied with it, would be executed with the privileges of the mmmail user.
