CVE-2013-1064 describes a local privilege escalation vulnerability in apt-xapian-index versions prior to 0.45ubuntu2.1, 0.44ubuntu7.1, and 0.44ubuntu5.1, affecting Canonical Ubuntu Linux. The flaw stems from improper D-Bus communication with a polkit authority, enabling local users to bypass access restrictions through a race condition involving PolkitUnixProcess PolkitSubject via setuid or pkexec processes. With a CVSS score of 4.6, this vulnerability has low attack complexity and requires local access, potentially leading to partial confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
