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 7% 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.

addresses: CWE-665

Ensures shared resources are explicitly initialized or cleared on allocation, preventing exposure of prior contents to new users or processes.

addresses: CWE-665

Mandates that every instance begins in a known (presumably clean) state, eliminating reliance on residual or uninitialized state left by prior executions.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly enforce proper resource initialization during coding and testing.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.

finds

Security testing can detect uninitialized variables but does not itself enforce initialization practices.

prevents

Configuration management can enforce secure defaults and initialization settings but is not the primary control for code-level initialization.

prevents

Secure development life cycle mandates initialization checks and secure defaults that directly prevent improper resource initialization.

prevents

Secure system architecture and engineering principles require explicit initialization of resources and secure state management.

prevents

Secure coding standards explicitly forbid uninitialized variables and mandate proper resource initialization before use.
