New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 7.4
SynopsisThe remote service has a buffer overflow.
DescriptionA heap overflow vulnerability exists in the version of exim installed on the remote host.
By sending a specially crafted message to the server, a remote attacker can leverage this vulnerability to execute arbitrary code on the server with the privilege of the exim server. A separate vulnerability that Nessus didn't test for, CVE-2010-4345, is often used to elevate the exim user to root access.
Note that Nessus checked for this vulnerability by sending a specially crafted packet and checking the response, without crashing the service.
All 4.6x versions 4.69-9 and below are known to be affected, and others may be as well.
SolutionUpgrade to version 4.70 as it addresses the issue.
