high Nessus Plugin ID 100111

Language:

Synopsis

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

Description

Timo Schmid of ERNW GmbH discovered that the Git git-shell, a restricted login shell for Git-only SSH access, allows a user to run an interactive pager by causing it to spawn 'git upload-pack --help'.

Solution

Upgrade the git packages.

For the stable distribution (jessie), this problem has been fixed in version 1:2.1.4-2.1+deb8u3.
