MiracleLinux 7 : libevent-2.0.21-4.0.1.el7.AXS7 (AXSA:2025-9720:01)
critical Nessus Plugin ID 282820
Synopsis
The remote MiracleLinux host is missing one or more security updates.Description
The remote MiracleLinux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the AXSA:2025-9720:01 advisory.The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached.
libevent is meant to replace the asynchronous event loop found in event driven network servers. An application just needs to call event_dispatch() and can then add or remove events dynamically without having to change the event loop.
Security fix(es):
- CVE-2016-10195: fix an out-of-bounds stack read in the name_parse function
- CVE-2016-10196: fix a stack-based buffer overflow in the evutil_parse_sockaddr_port function
- CVE-2016-10197: fix DoS via an empty hostname in the search_make_new function CVE(s):
CVE-2016-10197 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-2016-10195 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-2016-10196 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.
Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
