Synopsis

The remote Fedora host is missing a security update.

Description

Security fix for CVE-2020-5260 and CVE-2020-11008

CVE-2020-5260 - From the upstream [release notes](https://www.kernel.org/pub/software/scm/git/docs/RelNotes/2.17.
4.txt) :

> With a crafted URL that contains a newline in it, the credential > helper machinery can be fooled to give credential information for > a wrong host. The attack has been made impossible by forbidding > a newline character in any value passed via the credential > protocol.

CVE-2020-11008 - From the upstream [release notes](https://www.kernel.org/pub/software/scm/git/docs/RelNotes/2.17.
5.txt): > 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. > > Unlike the vulnerability CVE-2020-5260 fixed in v2.17.4, the > credentials are not for a host of the attacker's choosing; instead, > they are for some unspecified host (based on how the configured > credential helper handles an absent 'host' parameter). > > The attack has been made impossible by refusing to work with > under-specified credential patterns.
