K00409335: procps-ng vulnerability CVE-2018-1122
Original Publication Date: 29 Dec, 2020
Security Advisory Description
procps-ng before version 3.3.15 is vulnerable to a local privilege escalation
in top. If a user runs top with HOME unset in an attacker-controlled directory,
the attacker could achieve privilege escalation by exploiting one of several
vulnerabilities in the config_file() function. (CVE-2018-1122)
Impact
A local attacker can perform privilege escalation and cause a denial-of-service
(DoS) or execute malicious code.
Security Advisory Status
F5 Product Development has assigned ID 975605 (BIG-IP), ID 975605-7 (BIG-IQ),
and CPF-25225 (Traffix SDC) to this vulnerability.
To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. To determine if your
release is known to be vulnerable, the components or features that are affected
by the vulnerability, and for information about releases, point releases, or
hotfixes that address the vulnerability, refer to the following table. For more
information about security advisory versioning, refer to K51812227:

Security Advisory Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.
Mitigation
To mitigate this vulnerability, you should permit management access to F5
products only over a secure network and restrict command line access for
affected systems to only trusted users. For more information, refer to K13309:
Restricting access to the Configuration utility by source IP address (11.x -
16.x) and K13092: Overview of securing access to the BIG-IP system.

K16124204: procps-ng vulnerability CVE-2018-1124
Original Publication Date: 29 Dec, 2020
Security Advisory Description
procps-ng before version 3.3.15 is vulnerable to multiple integer overflows
leading to a heap corruption in file2strvec function. This allows a privilege

processes, which could result in crashes or arbitrary code execution in proc
utilities run by other users. (CVE-2018-1124)
Impact
A local attacker can perform privilege escalation and cause a denial-of-service
(DoS) or execute malicious code.
