Description:Summary:
The remote host is missing an update for the 'git' package(s) announced via the SSA:2020-105-01 advisory.

Vulnerability Insight:
New git packages are available for Slackware 14.0, 14.1, 14.2, and -current to
fix security issues.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/git-2.17.4-i586-1_slack14.2.txz: Upgraded.
This update fixes a security issue:
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. Credit for finding the
vulnerability goes to Felix Wilhelm of Google Project Zero.
