A recent security alert, identified as USN-6899-1, has shed light on a significant vulnerability within the GTK library, which is widely used in numerous applications. This vulnerability, cataloged under CVE ID CVE-2024-6655, poses a substantial risk as it could allow malicious entities to execute arbitrary code under certain conditions.
The core issue lies in the handling of module loading by the GTK library. Typically, libraries are expected to load additional modules from a set, predefined set of directories. However, due to a flaw in GTK's design, modules could be loaded from the current working directory instead. This is problematic, especially when GTK applications are launched from directories that are shared or can be written to by other users.
If exploited, this vulnerability could enable a local attacker to influence the behavior of a GTK application by injecting a malicious module into the application's launch directory. Such an injection could lead to arbitrary code execution with the privileges of the user running the application. In scenarios where the application is run with elevated privileges, the impact could be even more severe, potentially leading to full system compromise.
