CVSS v2.0
6.9
Média
| Vetor | AV:L/AC:M/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
sudo versions prior to 1.8.6p7
sudo versions 1.8.x prior to 1.8.6p6
sudo versions prior to 1.7.10p5
Description
The issue affects the sudo package in Gentoo Linux, potentially compromising confidentiality, integrity, and availability of protected information. Exploitation can occur locally. When the
tty tickets option is enabled, the controlling terminal device is not properly validated, allowing local users with sudo permissions to hijack the authorization of another terminal. This can be achieved via vectors related to a session without a controlling terminal device and connecting to the standard input, output, and error file descriptors of another terminal.Recommendations
For versions prior to 1.8.6p7, update to version 1.8.6p7 or later.
For versions 1.8.x prior to 1.8.6p6, update to version 1.8.6p6 or later.
For versions prior to 1.7.10p5, update to version 1.7.10p5 or later.
As a temporary workaround, consider disabling the
tty tickets option until a patch is available.Exploit
