Synopsis

The remote Debian host is missing a security-related 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.

Solution

Upgrade the git packages.

For the oldstable distribution (stretch), this problem has been fixed in version 1:2.11.0-3+deb9u6.

For the stable distribution (buster), this problem has been fixed in version 1:2.20.1-2+deb10u2.
