Package : libidn2
CVE ID : CVE-2019-18224
Debian Bug : 942895

A heap-based buffer overflow vulnerability was discovered in the
idn2_to_ascii_4i() function in libidn2, the GNU library for
Internationalized Domain Names (IDNs), which could result in denial of
service, or the execution of arbitrary code when processing a long
domain string.

For the stable distribution (buster), this problem has been fixed in
version 2.0.5-1+deb10u1.

We recommend that you upgrade your libidn2 packages.

For the detailed security status of libidn2 please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/libidn2
