Debian DSA-4159-1 : remctl - security update

high Nessus Plugin ID 108771

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Santosh Ananthakrishnan discovered a use-after-free in remctl, a server for Kerberos-authenticated command execution. If the command is configured with the sudo option, this could potentially result in the execution of arbitrary code.

The oldstable distribution (jessie) is not affected.

Solution

Upgrade the remctl packages.

For the stable distribution (stretch), this problem has been fixed in version 3.13-1+deb9u1.
