Ubuntu 6.06 LTS / 8.04 LTS / 9.10 : exim4 vulnerability (USN-1032-1)

High Nessus Plugin ID 51136

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


The remote Ubuntu host is missing one or more security-related patches.


Sergey Kononenko and Eugene Bujak discovered that Exim did not correctly truncate string expansions. A remote attacker could send specially crafted email traffic to run arbitrary code as the Exim user, which could also lead to root privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
