Vulnerability Title
Gnome-shell: gnome-shell: out-of-bounds read in remote search icon rendering due to unvalidated icon-data buffer size
Vulnerability Description
A flaw was found in GNOME Shell. When processing icons from a remote search provider via D-Bus, the system fails to validate the icon's declared dimensions against the actual data buffer size. A malicious or compromised remote search provider could exploit this by providing oversized icon dimensions, leading to an out-of-bounds read. This can cause the GNOME Shell process to crash, disrupting the user's session, and potentially disclose sensitive information from adjacent memory.
