CVE-2010-1163

Publication date 16 April 2010

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The command matching functionality in sudo 1.6.8 through 1.7.2p5 does not properly handle when a file in the current working directory has the same name as a pseudo-command in the sudoers file and the PATH contains an entry for ".", which allows local users to execute arbitrary commands via a Trojan horse executable, as demonstrated using sudoedit, a different vulnerability than CVE-2010-0426.

Notes

jdstrand

in Ubuntu 9.04 and earlier, sudo is compiled with secure_path, so a user must use sudoedit in sudoers and recompile sudo to not use secure_path. On Karmic, secure_path is configurable via suoders (but still set at compile-time). Ubuntu does not use 'ignore_dot' by default.
