CentOS Linux—the open, enterprise-class, platform upon which Lumeta solutions are builtand third-party packages such as Postgres and Oracle JRE—are continuously monitored by industry  and community groups to uncover flaws. Upgrade packages that fix these CentOS flaws (aka CVEs, Common Vulnerabilities and Exposures) are made available from CentOS and third parties (Postgres, Oracle JRE) on an ongoing basis. 

This page lists security enhancements on our radar.  It's those CVEs that Lumeta is actively addressing and expects to have fully resolved in the upcoming releases of Lumeta Enterprise Edition.

CVE-2021-4083kernel-3.10.0-1160.76.1.el7.x86_64
CentOS yesyes

A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system. This flaw affects Linux kernel versions prior to 5.16-rc4.

CVE-2021-4028kernel-3.10.0-1160.76.1.el7.x86_64
CentOS yesyes

A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system.

CVE-2022-0492

kernel-devel-3.10.0-1160.76.1.el7.x86_64


CentOS yesyes

A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.

python-2.7.5-92.el7_9.x86_64


CentOS yesyes

http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request.
