low Nessus Plugin ID 101032
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 is different from CVSS.

VPR Score: 1.4

Synopsis

The remote Debian host is missing a security update.

Description

Exim supports the use of multiple '-p' command line arguments which are malloc()'ed and never free()'ed, used in conjunction with other issues allows attackers to cause arbitrary code execution.

For Debian 7 'Wheezy', these problems have been fixed in version 4.80-7+deb7u5.

We recommend that you upgrade your exim4 packages.

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

Solution

Upgrade the affected packages.
