CVE-2013-1675
Canonical Ubuntu Linux 12.04 … 13.04
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2013-1675 is a medium-severity Improper Initialization (CWE-665) vulnerability in Canonical Ubuntu Linux. Its CVSS base score is 6.5 (Medium).
Operationally, ranked in the top 6% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Mozilla Firefox before version 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before 17.0.6, and Thunderbird ESR 17.x before 17.0.6 contain an improper initialization flaw in the nsDOMSVGZoomEvent::mPreviousScale and nsDOMSVGZoomEvent::mNewScale functions. The affected code fails to properly set up internal data structures for SVG zoom events, which is tracked as CWE-665 and carries a CVSS 3.1 score of 6.5 reflecting network attack vector, low complexity, and high confidentiality impact.
Remote attackers can exploit the issue by serving a crafted web page that triggers SVG zoom event handling in a vulnerable browser or mail client. Successful exploitation allows the attacker to read uninitialized memory contents from the process address space, potentially disclosing sensitive information such as cryptographic material or other process data, provided the user interacts with the malicious content.
The referenced OpenSUSE security advisories describe the availability of updated packages that correct the initialization error in the affected Mozilla components and advise administrators to apply the patches promptly to prevent information disclosure. No further details on in-the-wild exploitation are supplied in the source material.

Mitigating Controls
Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Ensures shared resources are explicitly initialized or cleared on allocation, preventing exposure of prior contents to new users or processes.
Mandates that every instance begins in a known (presumably clean) state, eliminating reliance on residual or uninitialized state left by prior executions.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.8.25 mandates security requirements, checkpoints, secure coding, testing and developer capability in the SDLC which reaches improper initialization as a design/coding defect, but leaves a bounded remainder (e.g. initialization of third-party components or libraries chosen in procurement, and post-deployment configuration defaults).
A.8.27 mandates security-by-design principles (least privilege, default-deny, fail-securely, distrust-external-input, hardening) plus explicit design reviews that can catch and block many uninitialized-resource cases before they ship, but leaves a bounded remainder (e.g. vendor libraries, runtime-initialization bugs, or post-review code changes) that can still be present and exploitable.
Secure coding standards explicitly forbid uninitialized variables and mandate proper resource initialization before use.
Security testing can detect uninitialized variables but does not itself enforce initialization practices.
defining, enforcing, and monitoring secure configuration templates (including defaults, disabled services, changed vendor passwords, minimized privileges) directly stops most improper-initialization cases from being exploitable; the bounded remainder is initialization logic inside custom application code that no configuration template reaches

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-665, a class-level weakness. Rules are authored against its narrower children: CWE-770.
