critical Tenable Cloud Security Plugin ID 400900

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- The name_parse function in evdns.c in libevent before 2.1.6-beta allows remote attackers to have
unspecified impact via vectors involving the label_len variable, which triggers an out-of-bounds stack
read. (CVE-2016-10195)

- 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. (CVE-2016-10196)

- The search_make_new function in evdns.c in libevent before 2.1.6-beta allows attackers to cause a denial
of service (out-of-bounds read) via an empty hostname. (CVE-2016-10197)
