A git security update has been released for Debian GNU/Linux 8 LTS.

DLA 2182-1: git security update

Package : git
Version : 1:2.1.4-2.1+deb8u10
CVE ID : CVE-2020-11008

Carlo Arenas discovered a flaw in git, a fast, scalable, distributed
revision control system. With a crafted URL that contains a newline or
empty host, or lacks a scheme, the credential helper machinery can be
fooled into providing credential information that is not appropriate for
the protocol in use and host being contacted.

For Debian 8 "Jessie", this problem has been fixed in version
1:2.1.4-2.1+deb8u10.

We recommend that you upgrade your git packages.
