Description

Valerio Costamagna discovered that sudo did not properly validate the pathfor the 'sudoedit' pseudo-command when the PATH contained only a dot ('.').If secure_path and ignore_dot were disabled, a local attacker could exploitthis to execute arbitrary code as root if sudo was configured to allow theattacker to use sudoedit. By default, secure_path is used and the sudoeditpseudo-command is not used in Ubuntu. This is a different but related issueto CVE-2010-0426. The problem can be corrected by updating your system to the following package version: To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades. In general, a standard system upgrade is sufficient to effect thenecessary changes. LP: 563963
