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.

Affected products named by the advisory: Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support; Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On; Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support; and 22 more.

Affected products named by the advisory: Red Hat Enterprise Linux 8.6 Telecommunications Update Service; Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions; Red Hat Enterprise Linux 8.8 Telecommunications Update Service; Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions; and 18 more.
