CVE-2022-48622
Description
A flaw was found in GNOME's GdkPixbuf library, a library used to load image data in various formats used by GDK for handling graphical assets. This issue occurs when loading a crafted ANI (animated cursor file) file, which may lead to a heap based out-of-bounds write, causing memory corruption. When a successful attack is in place, it can lead to a denial of service or in some cases arbitrary code execution.
Statement
The vulnerability in the GdkPixbuf library, allowing for heap-based out-of-bounds writes when loading crafted ANI files, poses a moderate severity risk. While the flaw could lead to memory corruption and potential denial of service or arbitrary code execution, its impact is somewhat mitigated by factors such as the need for the attacker to craft specifically malicious ANI files and the requirement for user interaction to open these files. Additionally, exploitation is limited to systems where GdkPixbuf is used to handle ANI files, reducing the overall attack surface.
Mitigation
This flaw can be mitigated by the user avoiding to load .ani files from untrusted sources.
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).

Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
