How to fix?

Upgrade SLES:16.0.0 glib2-doc to version 2.84.4-160000.4.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glib2-doc package and not the glib2-doc package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the G_REGEX_RAW compile flag and case-change replacement escapes because the string_append function processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a denial of service when the buffer over-read crosses a page boundary.
