What is CVE-2019-12749?

The vulnerability in the DBusServer implementation of DBUS_COOKIE_SHA1 allows a malicious user with write access to their home directory to forge cookie credentials through symlink manipulation. This can lead to unauthorized access as the DBusServer may incorrectly validate a reused cookie, enabling an attacker to impersonate different user identities, thereby bypassing standard authentication mechanisms.
