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.
