Package : sudo
Vulnerability : several
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2010-0426 CVE-2010-0427
Debian Bugs : 570737

Several vulnerabilities have been discovered in sudo, a program
designed to allow a sysadmin to give limited root privileges to users
database server.
The Common Vulnerabilities and Exposures project identifies the
following problems:


CVE-2010-0426:

It was discovered that sudo when a pseudo-command is enabled, permits a
match between the name of the pseudo-command and the name of an
executable file in an arbitrary directory, which allows local users to
gain privileges via a crafted executable file.


CVE-2010-0427:

It was discovered that sudo when the runas_default option is used, does
not properly set group memberships, which allows local users to gain privileges
via a sudo command.


For the stable distribution (lenny), these problems have been fixed in
version 1.6.9p17-2+lenny1

For the unstable distribution (sid), these problems have been fixed in
version 1.7.2p1-1.2, and will migrate to the testing distribution (squeeze)
shortly.

We recommend that you upgrade your sudo package.

Upgrade instructions
- --------------------

wget url

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
