Security readout for executives and security teams
Plain-English summary
CVE-2015-1341 is a local privilege escalation issue in Ubuntu Apport. A low-privileged user could abuse how Apport handled Python crash information to gain elevated privileges. It is high impact, but the provided sources do not show remote exploitation or confirmed active exploitation.
Executive priority
Prioritize remediation on multi-user Ubuntu systems and environments where local users are not fully trusted. This is not presented as remotely exploitable, but successful abuse could turn a limited account into broader system compromise.
Technical view
Apport before 2.19.2 could import arbitrary Python modules from sys.path when processing a coredump from a Python process whose command line used -m. The vulnerability requires local access with low privileges and can affect confidentiality, integrity, and availability due to changed scope and high impact ratings.
Likely exposure
Exposure is limited to Ubuntu systems running vulnerable Apport versions before 2.19.2. The bundle lists affected Ubuntu Apport versions as unspecified, so precise distro release exposure must be confirmed against Ubuntu USN-2782-1 and installed package versions.
Exploitation context
The CVSS vector indicates local access, low complexity, low privileges, no user interaction, and changed scope. The source bundle says KEV is false and provides no evidence of active exploitation. Treat it as a serious local privilege escalation, not a confirmed internet-exploited issue.
Researcher notes
The key condition is Apport's Python module path handling during Python coredump processing with -m. The bundle does not include affected Ubuntu release names, detailed patch diffs, exploit maturity, or workaround text, so validation should stay tied to vendor advisories.
Mitigation direction
- Apply Ubuntu security updates referenced by USN-2782-1.
- Upgrade Apport to 2.19.2 or a vendor-supported fixed package.
- Prioritize shared systems where untrusted users have shell access.
- Check Ubuntu guidance if fixed packages are unavailable.
Validation and detection
- Inventory Ubuntu hosts and installed Apport package versions.
- Compare versions against Ubuntu USN-2782-1 and Apport 2.19.2 guidance.
- Confirm whether Apport is installed and active on in-scope systems.
- Review patch records for the Ubuntu security update.
