Debian DLA-2177-1 : git security update

high Nessus Plugin ID 135596

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Felix Wilhelm of Google Project Zero discovered a flaw in git, a fast, scalable, distributed revision control system. With a crafted URL that contains a newline, the credential helper machinery can be fooled to return credential information for a wrong host.

For Debian 8 'Jessie', this problem has been fixed in version 1:2.1.4-2.1+deb8u9.

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.
