Debian DSA-4659-1 : git - security update

high Nessus Plugin ID 135794

Synopsis

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

Description

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.

Solution

Upgrade the git packages.

For the oldstable distribution (stretch), this problem has been fixed in version 1:2.11.0-3+deb9u7.

For the stable distribution (buster), this problem has been fixed in version 1:2.20.1-2+deb10u3.
