Hi,

The following vulnerability was published for libhangul.

CVE-2026-108063[0]:
| A flaw was found in libhangul. When parsing Hanja dictionary files,
| the library fails to verify that an entry contains a valid value
| alongside its key. By providing a specially crafted dictionary file
| to an application that queries it, an attacker can trigger an
| unexpected application crash, resulting in a Denial of Service
| (DoS).


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

IMO it's exaggerated. Debian is not affected.

Attackers can never provide a specially crafted dictionary file, as
all apps using libhangul don't support user provided dictionaries and
just load files in a fixed path. Input methods usually work like this.
Resulting in DoS? I believe that the reporter had no idea about what
libhangul is for.
