Denial of service via network
|
Fix Available: Yes Vendor Confirmed: Yes

Version(s): prior to 8.13.7

Description:
A vulnerability was reported in Sendmail. A remote user can cause denial of service conditions.
A remote user can send a specially crafted message containing malformed, deeply nested MIME content to cause excessive recursion, leading to stack exhaustion when the system attempts to deliver the message from the queue. Only mail delivered from the queue is affected. The system may fail to reattempt delivery of messages in the queue. Incoming mail is still accepted and delivered.
Also, if the system is configured to write uniquely named core dump files per process, the disk space may become filled with core dumps.
The vendor credits Frank Sheiness with reporting this vulnerability.

Impact:
A remote user may be able to stop the delivery of queued messages.
