CVE-2016-4574 is an off-by-one error in the Libksba library (specifically in the DN decoder's append_utf8_value function) that allows remote attackers to cause a denial of service through an out-of-bounds read when processing invalid UTF-8 encoded data. This vulnerability affects products from Canonical, GnuPG, and openSUSE, and is an incomplete fix for a previous vulnerability. With a CVSS v3 score of 7.5 (High), it can be exploited remotely with low attack complexity, leading to a complete loss of availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
