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)
