Package : libidn
Version : 1.29-1+deb8u3
CVE ID : CVE-2017-14062
Debian Bug : 873903

An integer overflow vulnerability was discovered in libidn, the GNU library for
Internationalized Domain Names (IDNs), in its Punycode handling (a Unicode
characters to ASCII encoding) allowing a remote attacker to cause a denial of
service against applications using the library.

For Debian 8 "Jessie", this problem has been fixed in version
1.29-1+deb8u3.

We recommend that you upgrade your libidn packages.
