Alpine: git: security update to 2.18.4-r0
high Tenable Self-Hosted Container Security Plugin ID 404613
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials
to a host controlled by an attacker. This bug is similar to CVE-2020-5260(GHSA-qm7j-c969-7j4q). The fix
for that bug still left the door open for an exploit where _some_ credential is leaked (but the attacker
cannot control which one). Git uses external "credential helper" programs to store and retrieve passwords
or other credentials from secure storage provided by the operating system. Specially-crafted URLs that are
considered illegal as of the recently published Git versions can cause Git to send a "blank" pattern to
helpers, missing hostname and protocol fields. Many helpers will interpret this as matching _any_ URL, and
will return some unspecified stored password, leaking the password to an attacker's server. The
vulnerability can be triggered by feeding a malicious URL to `git clone`. However, the affected URLs look
rather suspicious; the likely vector would be through systems which automatically clone URLs not visible
to the user, such as Git submodules, or package systems built around Git. The root of the problem is in
Git itself, which should not be feeding blank input to helpers. However, the ability to exploit the
vulnerability in practice depends on which helpers are in use. Credential helpers which are known to
trigger the vulnerability: - Git's "store" helper - Git's "cache" helper - the "osxkeychain" helper that
ships in Git's "contrib" directory Credential helpers which are known to be safe even with vulnerable
versions of Git: - Git Credential Manager for Windows Any helper not in this list should be assumed to
trigger the vulnerability. (CVE-2020-11008)
