CVE-2015-1326: python-dbusmock arbitrary code execution or file overwrite when templates are loaded from /tmp

python-dbusmock before version 0.15.1 AddTemplate() D-Bus method call or DBusTestCase.spawn_server_template() method could be tricked into executing malicious code if an attacker supplies a .pyc file.

Security readout for executives and security teams

Plain-English summary

This flaw affects python-dbusmock before 0.15.1 when loading templates. If an attacker can supply a malicious .pyc file, affected template-loading paths could execute code or overwrite files. The business risk is mainly to systems where this package is installed and used with untrusted or shared temporary template locations.

Executive priority

Prioritize as a moderate local-risk issue. Address during normal patch cycles unless python-dbusmock is used on shared systems or operational workflows load templates from writable temporary paths.

Technical view

CVE-2015-1326 involves python-dbusmock AddTemplate() over D-Bus and DBusTestCase.spawn_server_template(). Sources state versions before 0.15.1 could be tricked into executing malicious code if an attacker supplies a .pyc file, with risk tied to templates loaded from /tmp.

Likely exposure

Exposure is likely limited to Ubuntu environments with python-dbusmock installed, especially where vulnerable versions before 0.15.1 are present and template-loading functionality is used. The source bundle does not identify other vendors, products, or specific Ubuntu package versions.

Exploitation context

The CVSS vector indicates local access, low privileges, and user interaction. KEV is false, and the provided sources do not report active exploitation. Treat exploitation status as unconfirmed rather than active.

Researcher notes

Evidence is narrow: the record names python-dbusmock before 0.15.1, two affected APIs, malicious .pyc input, and /tmp template-loading context. No exploit details, patch notes beyond the referenced commit, or broad affected-product list are provided.

Mitigation direction

  • Upgrade python-dbusmock to 0.15.1 or later where available.
  • Check Ubuntu vendor guidance for package-specific remediation.
  • Avoid loading python-dbusmock templates from untrusted shared temporary locations.
  • Restrict write access to locations used for python-dbusmock templates.
  • Remove python-dbusmock where it is not required.

Validation and detection

  • Inventory systems for installed python-dbusmock packages.
  • Confirm installed versions are not earlier than 0.15.1.
  • Review code or tests using AddTemplate() or spawn_server_template().
  • Check whether template paths use /tmp or other shared writable directories.
  • Document any systems where vendor-fixed packages are unavailable.
