Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : sudo vulnerabilities (USN-905-1)

Ubuntu Security Notice (C) 2010-2016 Canonical, Inc. / NASL script (C) 2010-2016 Tenable Network Security, Inc.


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.

Solution :

Update the affected sudo and / or sudo-ldap packages.

Risk factor :

Medium / CVSS Base Score : 6.9
(CVSS2#AV:L/AC:M/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 6.0
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
