Description:
Matteo Memelli has discovered a vulnerability in MDaemon, which can be exploited by malicious users to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the IMAP server when processing the "FETCH" command. This can be exploited to cause a stack-based buffer overflow via a specially crafted "FETCH" command containing an overly long section specification in a "BODY" data item.
Successful exploitation allows execution of arbitrary code, but requires valid user credentials.
The vulnerability is confirmed in version 9.6.4. Other versions may also be affected.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, scan using the Network Software Inspector.
Solution:
Update to version 9.6.5.
