The remote EulerOS host is missing multiple security updates.
According to the versions of the libevent package installed, the
EulerOS installation on the remote host is affected by the following
- 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
- 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
- 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
Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
