What is CVE-2016-6263?

The stringprep_utf8_nfkc_normalize function in GNU libidn prior to version 1.33 is prone to vulnerabilities that allow attackers to exploit crafted UTF-8 data. This leads to context-dependent denial of service conditions, where an out-of-bounds read can occur, potentially causing an application crash. Users are advised to upgrade to the latest version to mitigate this risk.
