NewStart CGSL CORE 5.04 / MAIN 5.04 : chrony Multiple Vulnerabilities (NS-SA-2020-0027)

high Nessus Plugin ID 136904

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has chrony packages installed that are affected by multiple vulnerabilities:

 - Multiple integer overflows in pktlength.c in Chrony before 1.29 allow remote attackers to cause a denial of service (crash) via a crafted (1) REQ_SUBNETS_ACCESSED or (2) REQ_CLIENT_ACCESSES command request to the PKL_CommandLength function or crafted (3) RPY_SUBNETS_ACCESSED, (4) RPY_CLIENT_ACCESSES, (5) RPY_CLIENT_ACCESSES_BY_INDEX, or (6) RPY_MANUAL_LIST command reply to the PKL_ReplyLength function, which triggers an out-of-bounds read or buffer overflow. NOTE:
 versions 1.27 and 1.28 do not require authentication to exploit. (CVE-2012-4502)

 - cmdmon.c in Chrony before 1.29 allows remote attackers to obtain potentially sensitive information from stack memory via vectors related to (1) an invalid subnet in a RPY_SUBNETS_ACCESSED command to the handle_subnets_accessed function or (2) a RPY_CLIENT_ACCESSES command to the handle_client_accesses function when client logging is disabled, which causes uninitialized data to be included in a reply. (CVE-2012-4503)

 - Chrony before 1.29.1 has traffic amplification in cmdmon protocol (CVE-2014-0021)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL chrony packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
