Description
===========

- CVE-2018-18640 (information disclosure)

A security issue has been found in gitlab versions prior to 11.4.3,
where private project pages had inadequate cache control, which
resulted in unauthorized users being able to view them in the browser.

- CVE-2018-18641 (information disclosure)

A security issue has been found in gitlab versions prior to 11.4.3,
where personal access tokens were being stored unencrypted as plain
text in the database which could result in attackers potentially
reading them via SQL injection or other database leaks.

- CVE-2018-18643 (cross-site scripting)

A security issue has been found in gitlab versions prior to 11.4.3,
where the fragment identifier (hash) of several pages contained a lack
of input validation and output encoding issue which resulted in a
persistent XSS.

- CVE-2018-18645 (information disclosure)

A security issue has been found in gitlab versions prior to 11.4.3,
where when replying to an issue through email, with the GitLab email
footer included, a user's unsubscribe link would be included in the
issue. This information is considered sensitive.

- CVE-2018-18646 (cross-site request forgery)

A security issue has been found in gitlab versions prior to 11.4.3,
where the Hipchat integration was vulnerable to a SSRF issue which
allowed an attacker to make requests to any local network resource
accessible from the GitLab server.

- CVE-2018-18648 (information disclosure)

A security issue has been found in gitlab versions prior to 11.4.3,
where a JSON endpoint was disclosing Gem version information which
could result in an attacker discovering vulnerable Gems available on a
specific GitLab instance.

- CVE-2018-18649 (arbitrary code execution)

A security issue has been found in gitlab versions prior to 11.4.3,
where the wiki API contained an input validation issue which resulted
in remote code execution.

Impact
======

A remote attacker is able to execute arbitrary code, disclose
information, perform cross-site request forgery or cross-site
scripting.
