Package        : git
CVE ID         : CVE-2020-5260

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 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.

We recommend that you upgrade your git packages.

For the detailed security status of git please refer to its security
tracker page at:
