Source: golang-github-go-ldap-ldap
Version: 2.4.1-1
Severity: important
Tags: patch upstream security
Forwarded: https://github.com/go-ldap/ldap/pull/126


the following vulnerability was published for golang-github-go-ldap-ldap.

| In the ldap.v2 (aka go-ldap) package through 2.5.0 for Go, an attacker
| may be able to login with an empty password. This issue affects an
| application using this package if these conditions are met: (1) it
| relies only on the return error of the Bind function call to determine
| whether a user is authorized (i.e., a nil return value is interpreted
| as successful authorization) and (2) it is used with an LDAP server
| allowing unauthenticated bind.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
