CVE-2024-42415
Description
An integer overflow vulnerability was found in the Compound Document Binary File format parser of the GNOME Project G Structured File Library (libgsf). A specially crafted file can result in an integer overflow that allows for a heap-based buffer overflow when processing the sector allocation table, which can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
Statement
This vulnerability is classified as important severity rather than moderate due to its potential for arbitrary code execution, which poses a serious security risk. The integer overflow in the sector allocation table leads to a heap-based buffer overflow, allowing an attacker to write beyond the allocated memory bounds. Exploiting this flaw can result in memory corruption, enabling attackers to execute arbitrary code with the privileges of the affected application. Given that the vulnerability can be triggered by merely opening a specially crafted file, this expands the attack surface significantly, making exploitation feasible even through routine user actions like opening documents.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
