Описание
Stack-based buffer overflow in the evutil_parse_sockaddr_port function in evutil.c in libevent before 2.1.6-beta allows attackers to cause a denial of service (segmentation fault) via vectors involving a long string in brackets in the ip_as_string argument.
A vulnerability was found in libevent with the parsing of IPv6 addresses. If an attacker could cause an application using libevent to parse a malformed address in IPv6 notation of more than 2GiB in length, a stack overflow would occur leading to a crash.
