Debian DLA-938-1 : git security update

high Nessus Plugin ID 100110

Synopsis

The remote Debian host is missing a security 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'.

For Debian 7 'Wheezy', these problems have been fixed in version 1:1.7.10.4-1+wheezy4.

We recommend that you upgrade your git packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
