Ubuntu Security Notice 905-1 - 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. 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.

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.
