Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
It was discovered that sudo did not properly validate the path for the 'sudoedit' pseudo-command. A local attacker could exploit this to execute arbitrary code as root if sudo was configured to allow the attacker to use sudoedit. The sudoedit pseudo-command is not used in the default installation of Ubuntu. (CVE-2010-0426)It was discovered that sudo did not reset group permissions when the 'runas_default' configuration option was used. A local attacker could exploit this to escalate group privileges if sudo was configured to allow the attacker to run commands under the runas_default account.
The runas_default configuration option is not used in the default installation of Ubuntu. This issue affected Ubuntu 8.04 LTS, 8.10 and 9.04. (CVE-2010-0427).
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.
