CVE-2010-0426

Publication date 23 February 2010

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

sudo 1.6.x before 1.6.9p21 and 1.7.x before 1.7.2p4, 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, as demonstrated by a file named sudoedit in a user's home directory.

Notes

jdstrand

"Exploitation of the bug requires that the sudoers file be configured to allow the attacker to run sudoedit. If no users have been granted access to sudoedit there is no impact." Dapper has 1.6.8. If --secure-path is used and compiled to use execvp(), then sudo should not be vulnerable. Dapper is compiled with --secure-path and happens to use execvp()
