CVE-2014-1557

Description

From CVE.org

The ConvolveHorizontally function in Skia, as used in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7, does not properly handle the discarding of image data during function execution, which allows remote attackers to execute arbitrary code by triggering prolonged image scaling, as demonstrated by scaling of a high-quality image.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
