| Description: | Description:
The remote host is missing an update to sudo
announced via advisory USN-905-1.
Details follow:
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)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
sudo 1.6.8p12-1ubuntu6.1
sudo-ldap 1.6.8p12-1ubuntu6.1
Ubuntu 8.04 LTS:
sudo 1.6.9p10-1ubuntu3.6
sudo-ldap 1.6.9p10-1ubuntu3.6
Ubuntu 8.10:
sudo 1.6.9p17-1ubuntu2.2
sudo-ldap 1.6.9p17-1ubuntu2.2
Ubuntu 9.04:
sudo 1.6.9p17-1ubuntu3.1
sudo-ldap 1.6.9p17-1ubuntu3.1
Ubuntu 9.10:
sudo 1.7.0-1ubuntu2.1
sudo-ldap 1.7.0-1ubuntu2.1
In general, a standard system upgrade is sufficient to effect the
necessary changes.
