DSA-2062-1 sudo -- missing input sanitization

Debian Security Advisory

DSA-2062-1 sudo -- missing input sanitization

Date Reported:

17 Jun 2010

Affected Packages:

sudo

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 585394.
In Mitre's CVE dictionary: CVE-2010-1646.

More information:

Anders Kaseorg and Evan Broder discovered a vulnerability in sudo, a program designed to allow a sysadmin to give limited root privileges to users, that allows a user with sudo permissions on certain programs to use those programs with an untrusted value of PATH. This could possibly lead to certain intended restrictions being bypassed, such as the secure_path setting.

For the stable distribution (lenny), this problem has been fixed in version 1.6.9p17-3

For the unstable distribution (sid), this problem has been fixed in version 1.7.2p7-1, and will migrate to the testing distribution (squeeze) shortly.

We recommend that you upgrade your sudo package.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
