NewStart CGSL MAIN 4.05 : procps Multiple Vulnerabilities (NS-SA-2019-0155)

critical Nessus Plugin ID 127432
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 4.05, has procps packages installed that are affected by multiple vulnerabilities:

- Multiple integer overflows leading to heap corruption flaws were discovered in file2strvec(). These vulnerabilities can lead to privilege escalation for a local attacker who can create entries in procfs by starting processes, which will lead to crashes or arbitrary code execution in proc utilities run by other users (eg pgrep, pkill, pidof, w). (CVE-2018-1124)

- A flaw was found where procps-ng provides wrappers for standard C allocators that took `unsigned int` instead of `size_t` parameters. On platforms where these differ (such as x86_64), this could cause integer truncation, leading to undersized regions being returned to callers that could then be overflowed. The only known exploitable vector for this issue is CVE-2018-1124.
(CVE-2018-1126)

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 procps packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
