Security Advisory

1) Command injection

Description

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to command validation flaw in the get_process_ttyname() function. A local attacker can issue a specially crafted sudo command, cause the system to recognize the user's tty as an arbitrary file and overwrite arbitrary files. Exploitation of the bug is possible in case a malicious user has sudo privileges, the system contains SELinux and sudo has been built on SELinux support.

Successful exploitation of the vulnerability results in root access to the system.

Remediation

Update the affected package to version: 1.8.10p3-10.5.1.
