Summary
A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing malicious file or remote filesystem attribute values.
This vulnerability is rated Moderate for Red Hat products because an integer overflow in GLib's GIO `escape_byte_string()` function can lead to a heap buffer overflow and denial-of-service. This occurs when processing specially crafted file or remote filesystem attribute values, requiring an attacker to provide malicious input.
Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-190.
